Common Weakness Enumeration

CWE-89

Allowed

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Abstraction: Base · Status: Stable

The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

28869 vulnerabilities reference this CWE, most recent first.

CVE-2026-0544 (GCVE-0-2026-0544)

This advisory will also be published at https://documentation.open-xchange.com/dovecot/security/advisories/html/2026/oxdc-adv-2026-0003.html --- Classification: TLP:GREEN Internal reference: DOV-8476 Type: CWE-403 (Exposure of File Descriptor to Unintended Control Sphere ('File Descriptor Leak')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2025-11-25 Solution date: 2026-08-26 Disclosure date: 2026-08-26 CVE: CVE-2026-33263 CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) Details: submission-login: Panic when mail_max_userip_connections is reached: Panic: epoll_ctl(del, 8) failed: Bad file descriptor. When mail_max_userip_connections is set (defaul t 10) and reached, submission-login can crash with epoll() panic caused by file descriptor handling issues. Risk: If running in high-security mode (default for community releases), only the new submission connection gets terminated. If running in high-performance mode (default for Pr o releases), all connections handled by the submission-login process will be terminated. The crashes can cause failure for user to send a message, or it can cause duplica te messages to be sent. If TLS is not used (in the backend server processing the submission), duplicate deliveries cannot happen, because the crash can only happen at AUT H stage. No publicly available exploits are known. Solution: Limit the number of connections handled by single submission-login process. This has a performance impact though. Update to non-vulnerable version. --- Internal reference: DOV-8874 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <3.0.7, OX Dovecot Pro core >=3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-03-11 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: ylwango613@yeswehack CVE: CVE-2026-33607 CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) Details: Dovecot IMAP LIST match_sub() Exponential Backtracking — CPU Denial of Service. An attacker that has valid credentials can use IMAP LIST command to consume CPU. Risk: This can cause degradation or denial of service for IMAP. No publicly available exploits are known. Solution: Monitor system for abnormal CPU usage and kill the offending process and lock account. Alternatively install fixed version. --- Internal reference: DOV-8884 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-03-13 Solution date: 2026-08-26 Disclosure date: 2026-08-26 CVE: CVE-2026-27852 CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Details: DoS by sending mail with bad header. An attacker that can send mail to a user can craft a message whose headers contain a very large number of email addresses or MIME par ameters, which causes excessive memory usage when the message is later parsed. Risk: The message is still delivered, but reading it over IMAP can exhaust the memory limit of the process and terminate it, causing denial of service for the affected user. No publicly available exploits are known. Solution: Update to non-vulnerable version. --- Internal reference: DOV-8941 Type: CWE-93 (Improper Neutralization of CRLF Sequences ('CRLF Injection')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-03-24 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: thanos_haruki@yeswehack CVE: CVE-2026-33606 CVSS: 4.8 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:N) Details: dsync: Mail content can cause dsync protocol injection. Mail content stored by a user can be crafted so that it is interpreted as dsync protocol commands when an administ rator later runs dsync with the stream protocol, for example during a migration. Risk: Injected commands can modify mailbox state on the destination during migration or replication, including internal mailbox attributes that a user should not be able to set directly. It can also cause dsync errors. No publicly available exploits are known. Solution: Avoid running dsync with the stream protocol on mailboxes with untrusted content. Update to non-vulnerable version. --- Internal reference: DOV-8947 Type: CWE-655 (Insufficient Psychological Acceptability) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-03-24 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: heckintosh@yeswehack CVE: CVE-2026-33604 CVSS: 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N) Details: SMTP Smuggling via Missing Dot-Stuffing After Bare Carriage Return. An attacker that can get Dovecot to relay a message, for example through Sieve redirect or submission relay, can use a crafted line ending in the message body to bypass the outbound protection that prevents message content from being interpreted as SMTP commands. Risk: A downstream mail server that hasn't yet fixed the SMTP smuggling vulnerability can be tricked into treating part of the message body as new SMTP commands, allowing injec tion of spoofed email. This is the same vulnerability class as CVE-2023-51764 and CVE-2023-51766. No publicly available exploits are known. Solution: Where you control the receiving mail servers, ensure they reject bare carriage returns in message data. Update to non-vulnerable version. --- Internal reference: DOV-8949 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-03-24 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: djvirus@yeswehack CVE: CVE-2026-40014 CVSS: 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) Details: IMAP THREAD REFERENCES O(N²) CPU DoS via Crafted References Header (index-thread-links.c). An attacker that can send mail to a user can craft a message header that makes the IMAP THREAD command consume CPU disproportionate to the size of the message. Risk: When a mail client issues a THREAD command on the affected mailbox, this can cause degradation or denial of service for IMAP. No publicly available exploits are known. Solution: Monitor system for abnormal CPU usage, kill the offending process and remove the offending message from the affected mailbox. Update to non-vulnerable version. --- Internal reference: DOV-8991 Type: CWE-124 (Buffer Underwrite ('Buffer Underflow')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-04-02 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: ilyar@yeswehack CVE: CVE-2026-40013 CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) Details: pigeonhole: Stack Buffer Underflow in Pigeonhole ManageSieve CHECKSCRIPT/PUTSCRIPT. An attacker that has valid credentials can submit a Sieve script containing an extreme numeric literal, which causes an out-of-bounds write when the ManageSieve service compiles the script. Risk: This causes memory corruption and an observed crash of the ManageSieve process, resulting in denial of service for script management. This might be able to be used for re mote code execution. No publicly available exploits are known. Solution: Disable the ManageSieve service if users do not need remote Sieve script management. Update to non-vulnerable version. --- Internal reference: DOV-8994 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core =3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-04-02 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: ilyar@yeswehack CVE: CVE-2026-33605 CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Details: managesieve-login: Pre-auth crash. An unauthenticated attacker can crash the ManageSieve login process by sending a small malformed command before authenticating. Risk: If running in high-security mode (default for community releases), only the attacker's own connection is terminated. If running in high-performance mode (default for Pro releases), all connections handled by the same managesieve-login process are terminated. Repeating the attack can cause denial of service for Sieve script management. No publicly available exploits are known. Solution: Restrict network access to the ManageSieve service to trusted clients. Update to non-vulnerable version. --- Internal reference: DOV-9039 Type: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Affected versions: OX Dovecot Pro core >=2.3.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5 First fixed revision: OX Dovecot Pro core 3.1.6, OX Dovecot CE core 2.4.5 Discovery date: 2026-04-08 Solution date: 2026-08-26 Disclosure date: 2026-08-26 Researcher credits: tipsennn@yeswehack CVE: CVE-2026-40018 CVSS: 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) Details: MySQL multi-byte escaping wrong.

Update to non-vulnerable version.\n\n\n\n---\n\n\n\nInternal reference: DOV-8994\nType: CWE-400 (Uncontrolled Resource Consumption)\nComponent: core\nReport confidence: Confirmed\nSolution status: Fixed by vendor\nAffected versions: OX Dovecot Pro core \u003e=2.3.0 \u003c2.3.22.2, OX Dovecot Pro core \u003e=3.0.0 \u003c3.0.7, OX Dovecot Pro core \n=3.1.0 \u003c3.1.6, OX Dovecot CE core \u003e=2.3.0 \u003c2.4.5\nFirst fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE \ncore 2.4.5\nDiscovery date: 2026-04-02\nSolution date: 2026-08-26\nDisclosure date: 2026-08-26\nResearcher credits: ilyar@yeswehack\nCVE: CVE-2026-33605\nCVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)\n\nDetails:\nmanagesieve-login: Pre-auth crash. An unauthenticated attacker can crash the ManageSieve login process by sending a \nsmall malformed command before authenticating.\n\nRisk:\nIf running in high-security mode (default for community releases), only the attacker\u0027s own connection is terminated. If \nrunning in high-performance mode (default for Pro \nreleases), all connections handled by the same managesieve-login process are terminated. Repeating the attack can cause \ndenial of service for Sieve script management.

Summary
Dear subscribers, we're sharing our latest advisory with you and like to thank everyone who contributed in finding and solving those vulnerabilities. This advisory is also published at https://documentation.open-xchange.com/dovecot/security/advisories/html/2026/oxdc-adv-2026-0001.html --- Classification: TLP:GREEN Internal reference: DOV-7830 Type: CWE-1250 (Improper Preservation of Consistency Between Independent Representations of Shared State) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot CE core 2.4.1 Discovery date: 2025-07-24 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: Erik <erik () broadlux com> CVE: CVE-2025-30189 CVSS: 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) Details: v2.4 regression: auth cache broken with several passdb / userdb. When cache is enabled, some passdb/userdb drivers incorrectly cache all users with same cache key, causing wrong cached information to be used for these users. Risk: After cached login, all subsequent logins are for same user. No publicly available exploits are known. Solution: Install fixed version or disable caching either globally or for the impacted passdb/userdb drivers. --- Internal reference: DOV-8349 Type: CWE-20 (Improper Input Validation) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot Pro core 3.1.2, OX Dovecot CE core 2.4.3 Discovery date: 2025-11-04 Solution date: 2026-03-27 Disclosure date: 2026-03-27 CVE: CVE-2025-59028 CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) Details: Invalid base64 authentication can cause DoS for other logins. When sending invalid base64 SASL data, login process is disconnected from the auth server, causing all active authentication sessions to fail. Risk: Invalid BASE64 data can be used to DoS a vulnerable server to break concurrent logins. No publicly available exploits are known. Solution: Install fixed version or disable concurrency in login processes (heavy perfomance penalty on large deployments). --- Internal reference: DOV-8508 Type: CWE-20 (Improper Input Validation) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.3 Discovery date: 2025-11-29 Solution date: 2026-03-27 Disclosure date: 2026-03-27 CVE: CVE-2025-59032 CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Details: v2.4/v3.1 regression: Pigeonhole: ManageSieve panic occurs with sieve-connect as a client. ManageSieve AUTHENTICATE command crashes when using literal as SASL initial response. Risk: This can be used to crash ManageSieve service repeatedly, making it unavailable for other users. No publicly available exploits are known. Solution: Control access to ManageSieve port, or disable the service if it's not needed. Alternatively upgrade to a fixed version. --- Internal reference: DOV-8584 Type: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 2.3.0 First fixed revision: OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.3, OX Dovecot Pro core 2.3.22.1 Discovery date: 2025-12-29 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: cavid@yeswehack CVE: CVE-2025-59031 CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) Details: decode2text.sh OOXML extraction may follow symlinks and read unintended files during indexing. Dovecot has provided a script to use for attachment to text conversion. This script unsafely handles zip-style attachments. Risk: Attacker can use specially crafted OOXML documents to cause unintended files on the system to be indexed and subsequently ending up in FTS indexes. No publicly available exploits are known. Solution: Do not use the provided script, instead, use something else like FTS tika. --- Internal reference: DOV-8591 Type: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 2.3.0 First fixed revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 Discovery date: 2026-01-07 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: strokep@yeswehack CVE: CVE-2026-0394 CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) Details: auth: Path traversal in passwd-file passdb using `%d` (domain) escapes base directory and opens `/etc/passwd`Pre-auth path traversal in passwd-file passdb using `%d` (domain) escapes base directory and opens `/etc/passwd`. When dovecot has been configured to use per-domain passwd files, and they are placed one path component above /etc, or slash has been added to allowed characters, path traversal can happen if the domain component is directory partial. Risk: This allows inadvertently reading /etc/passwd (or some other path which ends with passwd). If this file contains passwords, it can be used to authenticate wrongly, or if this is userdb, it can unexpectly make system users appear valid users. No publicly available exploits are known. Solution: Upgrade to fixed version, or use different authentication scheme that does not rely on paths. Alternatively you can also ensure that the per-domain passwd files are in some other location, such as /etc/dovecot/auth/%d. --- Internal reference: DOV-8775 Type: CWE-90 (Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4 Discovery date: 2026-02-20 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: cookiejack15@yeswehack CVE: CVE-2026-27860 CVSS: 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N) Details: v2.4/v3.1 regression: auth-ldap is not escaping usernames. If auth_username_chars is empty, it is possible to inject arbitrary LDAP filter to Dovecot's LDAP authentication. Risk: This leads to potentially bypassing restrictions and allows probing of LDAP structure. No publicly available exploits are known. Solution: Do not clear out auth_username_chars, or install fixed version. --- Internal reference: DOV-8781 Type: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4 Discovery date: 2026-02-23 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: whisperer@yeswehack CVE: CVE-2026-24031 CVSS: 7.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:L) Details: v2.4/v3.1 regression: SQL injection allows bypassing authentication. Dovecot SQL based authentication can be bypassed when auth_username_chars is cleared by admin. Risk: This vulnerability allows bypassing authentication for any user and user enumeration. No publicly available exploits are known. Solution: Do not clear auth_username_chars. If this is not possible, install latest fixed version. --- Internal reference: DOV-8787 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 3.0.2, OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot Pro core 3.0.5, OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4 Discovery date: 2026-02-24 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: djvirus@yeswehack CVE: CVE-2026-27859 CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) Details: v3.0.2+ regression: Message headers MIME parameter parsing can cause excessive CPU usage. A mail message containing excessive amount of RFC 2231 MIME parameters causes LMTP to use too much CPU. Risk: A suitably formatted mail message causes mail delivery process to consume large amounts of CPU time. No publicly available exploits are known. Solution: Use MTA capabilities to limit RFC 2231 MIME parameters in mail messages, or upgrade to fixed version where the processing is limited. --- Internal reference: DOV-8816 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 2.3.0 First fixed revision: OX Dovecot Pro core 3.0.5, OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4, OX Dovecot Pro core 2.3.22.1 Discovery date: 2026-02-27 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: whisperer@yeswehack CVE: CVE-2026-27857 CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) Details: imap-login: Excessive memory usage DoS. Sending "NOOP (((...)))" command with 4000 parenthesis open+close results in ~1MB extra memory usage. Longer commands will result in client disconnection. This 1 MB can be left allocated for longer time periods by not sending the command ending LF. So attacker could connect possibly from even a single IP and create 1000 connections to allocate 1 GB of memory, which would likely result in reaching VSZ limit and killing the process and its other proxied connections. Risk: Attacker could connect possibly from even a single IP and create 1000 connections to allocate 1 GB of memory, which would likely result in reaching VSZ limit and killing the process and its other proxied connections. No publicly available exploits are known. Solution: Install fixed version, there is no other remediation. --- Internal reference: DOV-8818 Type: CWE-400 (Uncontrolled Resource Consumption) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 2.3.0, OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0 First fixed revision: OX Dovecot Pro core 3.0.5, OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4, OX Dovecot Pro core 2.3.22.1 Discovery date: 2026-02-28 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: ilyar@yeswehack CVE: CVE-2026-27858 CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Details: managesieve-login out-of-memory DoS. Attacker can send a specifically crafted message before authentication that causes managesieve to allocate large amount of memory. Risk: Attacker can force managesieve-login to be unavailable by repeatedly crashing the process. No publicly available exploits are known. Solution: Protect access to managesieve protocol, or install fixed version. --- Internal reference: DOV-8830 Type: CWE-287 (Improper Authentication) Component: core Report confidence: Confirmed Solution status: Fixed by vendor Last affected revision: OX Dovecot Pro core 2.3.0 First fixed revision: OX Dovecot Pro core 3.0.5, OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4, OX Dovecot Pro core 2.3.22.1 Discovery date: 2026-03-04 Solution date: 2026-03-27 Disclosure date: 2026-03-27 Researcher credits: bksparajuli@yeswehack CVE: CVE-2026-27856 CVSS: 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N) Details: doveadm: Credentials verified without timing safety.

When dovecot \nhas been configured to use per-domain passwd files, and they are placed one path component above /etc, or slash has \nbeen added to allowed characters, path traversal can happen if the domain component is directory partial.\n\nRisk:\nThis allows inadvertently reading /etc/passwd (or some other path which ends with passwd). If this file contains \npasswords, it can be used to authenticate wrongly, or if this is userdb, it can unexpectly make system users appear \nvalid users.  No publicly available exploits are known.\n\nSolution:\nUpgrade to fixed version, or use different authentication scheme that does not rely on paths. Alternatively you can \nalso ensure that the per-domain passwd files are in some other location, such as /etc/dovecot/auth/%d.\n\n\n\n---\n\n\n\nInternal reference: DOV-8775\nType: CWE-90 (Improper Neutralization of Special Elements used in an LDAP Query (\u0027LDAP Injection\u0027))\nComponent: core\nReport confidence: Confirmed\nSolution status: Fixed by vendor\nLast affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0\nFirst fixed revision: OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.4\nDiscovery date: 2026-02-20\nSolution date: 2026-03-27\nDisclosure date: 2026-03-27\nResearcher credits: cookiejack15@yeswehack\nCVE: CVE-2026-27860\nCVSS: 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)\n\nDetails:\nv2.4/v3.1 regression: auth-ldap is not escaping usernames.

Title
[SYSS-2025-009] Linksys MX9600/MX4200 - SQL Injection
Summary
Advisory ID:               SYSS-2025-009 Product:                   MR9600, MX4200 (and potentially others) Manufacturer:              Linksys Tested Version(s):         1.0.4.205530 for MR9600, 1.0.13.210200 for MX4200 Vulnerability Type:        SQL Injection (CWE-89) Risk Level:                High Solution Status:           Open Manufacturer Notification: 2025-03-18 Solution Date:             - Public Disclosure:         2026-02-12 CVE Reference:             Not yet assigned Author of Advisory:        Christian Zäske, SySS GmbH ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Overview: Linksys MX4200 is a Wi-Fi mesh router targeting home users. The manufacturer describes the product as follows (see [1]): "This router supports the latest Wi-Fi® 6 (802.11ax) standard for next-level streaming and gaming. Its powerful WiFi 6 mesh coverage offers faster WiFi performance for lag-free online gaming and simultaneous streaming to every device and corner of your home." Due to improper neutralization of special elements, SQL statements can be injected via the handshake of a TLS-SRP connection. This can be used to inject known credentials into the database. These credentials can be utilized to successfully complete the handshake and use the protected service. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The Linksys MX4200 (and other models) provides a service (sct_server binary) running on TCP port 6060 (all interfaces except WAN), which is used to integrate other mesh devices into the network. The service accepts TLS-SRP connections with a username and password. The service uses a different script (smcdb_auth) to receive credential information from an SQLite databse using the given username. Since the service does not properly neutralize special elements in the username, arbitrary SQL statements can be injected. This can be used to insert known credentials into the correct database table, which then provide access to the protected service (sct_server). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): Using the "tlslite-ng" library, the following Python code will inject known credentials into the "authorize" table of the used SQLite database. These credentials can be used to access the service.   from socket import *   from tlslite.api import *   from tlslite import *   N, g, salt, verifier = VerifierDB.makeVerifier("SySS", "SySS", 1024)   verifier_bytes = verifier.to_bytes(128)   sock = socket.socket(AF_INET, SOCK_STREAM)   sock.connect(("192.168.1.1", 6060))   conn = TLSConnection(sock)   try:   except:       pass   for byte in verifier_bytes:       sock = socket.socket(AF_INET, SOCK_STREAM)       sock.connect(("192.168.1.1", 6060))       conn = TLSConnection(sock)       try:       except:           pass After the code is executed, the TLS-SRP handshake will successfully complete when authenticating with the username "SySS" and the password "SySS". ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: There is no known solution yet. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2025-01-30: Vulnerability discovered 2025-03-18: Vulnerability reported to manufacturer 2025-04-07: First response from manufacturer 2025-04-14: Requested an update from manufacturer 2025-05-06: Acknowledgment of vulnerabilities by the manufacturer 2026-02-12: Public disclosure ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ References: [1] Product website for Linksys MX4200     https://support.linksys.com/kb/article/952-en/ [2] SySS Security Advisory SYSS-2025-009 https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2025-009.txt [3] SySS Responsible Disclosure Policy     https://www.syss.de/en/responsible-disclosure-policy ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Credits: This security vulnerability was found by Christian Zäske of SySS GmbH.

Its powerful WiFi 6 mesh coverage\noffers faster WiFi performance for lag-free online gaming and\nsimultaneous streaming to every device and corner of your home.\"\n\nDue to improper neutralization of special elements, SQL statements can\nbe injected via the handshake of a TLS-SRP connection. This can be used\nto inject known credentials into the database. These credentials can be\nutilized to successfully complete the handshake and use the protected\nservice.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nVulnerability Details:\n\nThe Linksys MX4200 (and other models) provides a service (sct_server\nbinary) running on TCP port 6060 (all interfaces except WAN), which is\nused to integrate other mesh devices into the network. The service\naccepts TLS-SRP connections with a username and password.\n\nThe service uses a different script (smcdb_auth) to receive credential\ninformation from an SQLite databse using the given username. Since the\nservice does not properly neutralize special elements in the username,\narbitrary SQL statements can be injected. This can be used to insert\nknown credentials into the correct database table, which then provide\naccess to the protected service (sct_server).\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nProof of Concept (PoC):\n\nUsing the \"tlslite-ng\" library, the following Python code will inject\nknown credentials into the \"authorize\" table of the used SQLite database.\nThese credentials can be used to access the service.\n\n\u00a0 from socket import *\n\u00a0 from tlslite.api import *\n\u00a0 from tlslite import *\n\n\u00a0 N, g, salt, verifier = VerifierDB.makeVerifier(\"SySS\", \"SySS\", 1024)\n\u00a0 verifier_bytes = verifier.to_bytes(128)\n\n\u00a0 sock = socket.socket(AF_INET, SOCK_STREAM)\n\u00a0 sock.connect((\"192.168.1.1\", 6060))\n\n\u00a0 conn = TLSConnection(sock)\n\u00a0 try:\n\n\u00a0 except:\n\u00a0 \u00a0 \u00a0 pass\n\n\u00a0 for byte in verifier_bytes:\n\u00a0 \u00a0 \u00a0 sock = socket.socket(AF_INET, SOCK_STREAM)\n\u00a0 \u00a0 \u00a0 sock.connect((\"192.168.1.1\", 6060))\n\u00a0 \u00a0 \u00a0 conn = TLSConnection(sock)\n\u00a0 \u00a0 \u00a0 try:\n\n\u00a0 \u00a0 \u00a0 except:\n\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 pass\n\n\nAfter the code is executed, the TLS-SRP handshake will successfully\ncomplete when authenticating with the username \"SySS\" and the\npassword \"SySS\".\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nSolution:\n\nThere is no known solution yet.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclosure Timeline:\n\n2025-01-30: Vulnerability discovered\n2025-03-18: Vulnerability reported to manufacturer\n2025-04-07: First response from manufacturer\n2025-04-14: Requested an update from manufacturer\n2025-05-06: Acknowledgment of vulnerabilities by the manufacturer\n2026-02-12: Public disclosure\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nReferences:\n\n[1] Product website for Linksys MX4200\n\u00a0 \u00a0 https://support.linksys.com/kb/article/952-en/\n[2] SySS Security Advisory SYSS-2025-009\nhttps://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2025-009.txt\n[3] SySS Responsible Disclosure Policy\n\u00a0 \u00a0 https://www.syss.de/en/responsible-disclosure-policy\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nCredits:\n\nThis security vulnerability was found by Christian Z\u00e4ske of SySS\nGmbH.\n\nE-Mail: christian.zaeske () syss de\n\nKey ID: 0x7B00D164A32F9AC9\nKey Fingerprint: 51D4 6E9B 3C29 7347 AC01 0F5A 7B00 D164 A32F 9AC9\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclaimer:\n\nThe information provided in this security advisory is provided \"as is\"\nand without warranty of any kind.

Summary
0day Rubbish Research Team is publicly disclosing two vulnerabilities in Leostream Connection Broker 9.1.37.0. Vulnerability 1 — Authenticated SQL injection to webshell to root RCE (CVSS 9.1, CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H, CWE-89) call_back.pl?action=user concatenates the unsigned _where parameter into a PostgreSQL WHERE clause; the default installation grants SUPERUSER, runs postgres as the webroot owner, and configures NOPASSWD sudo, so lo_export writes a webshell and /welcome.pl?c= triggers commands as root. Vulnerability 2 — Unauthenticated rogue-agent registration + SSRF (CVSS 7.0, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N, CWE-306) Server.Register is dispatched without the session gate and its token check is optional, letting an anonymous caller inject VM records and drive broker outbound TLS connections to attacker-controlled hosts.

Mitigation MIT-4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
  • For example, consider using persistence layers such as Hibernate or Enterprise Java Beans, which can provide significant protection against SQL injection if used properly.
Mitigation MIT-27
Architecture and Design

Strategy: Parameterization

  • If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
  • Process SQL queries using prepared statements, parameterized queries, or stored procedures. These features should accept parameters or variables and support strong typing. Do not dynamically construct and execute query strings within these features using "exec" or similar functionality, since this may re-introduce the possibility of SQL injection. [REF-867]
Mitigation MIT-17
Architecture and Design Operation

Strategy: Environment Hardening

  • Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
  • Specifically, follow the principle of least privilege when creating user accounts to a SQL database. The database users should only have the minimum privileges necessary to use their account. If the requirements of the system indicate that a user can read and modify their own data, then limit their privileges so they cannot read/write others' data. Use the strictest permissions possible on all database objects, such as execute-only for stored procedures.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation MIT-28
Implementation

Strategy: Output Encoding

  • While it is risky to use dynamically-generated query strings, code, or commands that mix control and data together, sometimes it may be unavoidable. Properly quote arguments and escape any special characters within those arguments. The most conservative approach is to escape or filter all characters that do not pass an extremely strict allowlist (such as everything that is not alphanumeric or white space). If some special characters are still needed, such as white space, wrap each argument in quotes after the escaping/filtering step. Be careful of argument injection (CWE-88).
  • Instead of building a new implementation, such features may be available in the database or programming language. For example, the Oracle DBMS_ASSERT package can check or enforce that parameters have certain properties that make them less vulnerable to SQL injection. For MySQL, the mysql_real_escape_string() API function is available in both C and PHP.
Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • When constructing SQL query strings, use stringent allowlists that limit the character set based on the expected value of the parameter in the request. This will indirectly limit the scope of an attack, but this technique is less important than proper output encoding and escaping.
  • Note that proper output encoding, escaping, and quoting is the most effective solution for preventing SQL injection, although input validation may provide some defense-in-depth. This is because it effectively limits what will appear in output. Input validation will not always prevent SQL injection, especially if you are required to support free-form text fields that could contain arbitrary characters. For example, the name "O'Reilly" would likely pass the validation step, since it is a common last name in the English language. However, it cannot be directly inserted into the database because it contains the "'" apostrophe character, which would need to be escaped or otherwise handled. In this case, stripping the apostrophe might reduce the risk of SQL injection, but it would produce incorrect behavior because the wrong name would be recorded.
  • When feasible, it may be safest to disallow meta-characters entirely, instead of escaping them. This will provide some defense in depth. After the data is entered into the database, later processes may neglect to escape meta-characters before use, and you may not have control over those processes.
Mitigation MIT-21
Architecture and Design

Strategy: Enforcement by Conversion

When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.

Mitigation MIT-39
Implementation
  • Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
  • If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
  • Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
  • In the context of SQL Injection, error messages revealing the structure of a SQL query can help attackers tailor successful attack strings.
Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481.

Mitigation MIT-16
Operation Implementation

Strategy: Environment Hardening

When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.

CAPEC-108: Command Line Execution through SQL Injection

An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

CAPEC-109: Object Relational Mapping Injection

An attacker leverages a weakness present in the database access layer code generated with an Object Relational Mapping (ORM) tool or a weakness in the way that a developer used a persistence framework to inject their own SQL commands to be executed against the underlying database. The attack here is similar to plain SQL injection, except that the application does not use JDBC to directly talk to the database, but instead it uses a data access layer generated by an ORM tool or framework (e.g. Hibernate). While most of the time code generated by an ORM tool contains safe access methods that are immune to SQL injection, sometimes either due to some weakness in the generated code or due to the fact that the developer failed to use the generated access methods properly, SQL injection is still possible.

CAPEC-110: SQL Injection through SOAP Parameter Tampering

An attacker modifies the parameters of the SOAP message that is sent from the service consumer to the service provider to initiate a SQL injection attack. On the service provider side, the SOAP message is parsed and parameters are not properly validated before being used to access a database in a way that does not use parameter binding, thus enabling the attacker to control the structure of the executed SQL query. This pattern describes a SQL injection attack with the delivery mechanism being a SOAP message.

CAPEC-470: Expanding Control over the Operating System from the Database

An attacker is able to leverage access gained to the database to read / write data to the file system, compromise the operating system, create a tunnel for accessing the host machine, and use this access to potentially attack other machines on the same network as the database machine. Traditionally SQL injections attacks are viewed as a way to gain unauthorized read access to the data stored in the database, modify the data in the database, delete the data, etc. However, almost every data base management system (DBMS) system includes facilities that if compromised allow an attacker complete access to the file system, operating system, and full access to the host running the database. The attacker can then use this privileged access to launch subsequent attacks. These facilities include dropping into a command shell, creating user defined functions that can call system level libraries present on the host machine, stored procedures, etc.

CAPEC-66: SQL Injection

This attack exploits target software that constructs SQL statements based on user input. An attacker crafts input strings so that when the target software constructs SQL statements based on the input, the resulting SQL statement performs actions other than those the application intended. SQL Injection results from failure of the application to appropriately validate input.

CAPEC-7: Blind SQL Injection

Blind SQL Injection results from an insufficient mitigation for SQL Injection. Although suppressing database error messages are considered best practice, the suppression alone is not sufficient to prevent SQL Injection. Blind SQL Injection is a form of SQL Injection that overcomes the lack of error messages. Without the error messages that facilitate SQL Injection, the adversary constructs input strings that probe the target through simple Boolean SQL expressions. The adversary can determine if the syntax and structure of the injection was successful based on whether the query was executed or not. Applied iteratively, the adversary determines how and where the target is vulnerable to SQL Injection.
