Title
sdbootutil: world-readable debug log
Summary
On request the `sdbootutil` script creates a world-readable debug log in /var/log/sdbootutil.log. The log file is created world-readable, however, which means that arbitrary low-privileged users in the system will be able to extract secrets from it.

Title
AsyncHttpClient: Resumable download index store is created world-readable and follows a planted symlink
Summary
The AsyncHttpClient library allows Java applications to execute HTTP requests and asynchronously process HTTP responses. From 2.0.0 until 2.16.1 and 3.0.12, PropertiesBasedResumableProcessor stores resumable download state at the predictable shared path $java.io.tmpdir/ahc/ResumableAsyncHandler.properties with default permissions and link-following file operations. A local user who can read the shared store can see download URLs, including embedded user information or query tokens. A local user who can write within or pre-create the affected shared store directory can plant a symbolic link that the client follows when saving state, truncating and overwriting a target file writable by the client process. The filesystem path is used when ResumableAsyncHandler decorates another AsyncHandler, while the no-argument constructors use a no-op processor and are unaffected. This issue is fixed in versions 2.16.1 and 3.0.12.

Title
adm-zip extraction preserves SUID/SGID bits from untrusted ZIPs -> local privilege escalation
Summary
adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js. Prior to 0.6.1, adm-zip applies the Unix permission bits stored in a zip entry directly to the extracted file via `fs.chmodSync()` when `keepOriginalPermission=true` is passed to `extractAllTo()`/`extractEntryTo()` — and it never filters the setuid/setgid/sticky bits out of those bits. A zip crafted by an attacker can therefore produce an extracted binary with mode `04755`. When extraction runs as root (the default posture in Docker builds, CI runners, and privileged install steps — the exact environments where this flag is used), the resulting root-owned setuid file is executed later by a lesser-privileged user, turning the attacker's code into a root execution. Version 0.6.1 fixes the issue.

Title
EA Javelin Anticheat Installer Local Privilege Escalation
Summary
Incorrect permission assignment (CWE-732) in the standalone installer for EA Javelin Anticheat (versions 1.0.14329371, 1.0.14547437, 1.0.14789537, and 1.0.14940698) on Windows allows a local non-administrative user to elevate privileges to NT AUTHORITY\SYSTEM by modifying the EAAntiCheatService service configuration and executable path. This vulnerability requires non-standard manual execution of the standalone installer and does not affect standard game installations via the EA App and Steam. This issue is corrected in version 1.0.14940699 and later; service permissions automatically self-heal upon launching an integrated EA game title.

Title
MISP Installer Log and FIFO Created World-Readable, Exposing Sensitive Credentials
Summary
The MISP installer scripts (for Debian 12, Debian 13, Ubuntu 24.04, and RHEL 9.4) create a log file at /var/log/misp_install.log and a named pipe (FIFO) at /var/log/misp_install.log.pipe to capture all installer output. The log captures highly sensitive data including the generated admin password, database passwords, GPG passphrase, and supervisor password. However, the log file was created by the tee command under the system default umask, resulting in world-readable permissions (typically 0644). Similarly, the FIFO was created with mkfifo without an explicit mode, also inheriting the default umask and remaining world-readable during the window before it was unlinked.
Any local unprivileged user on the system could read the log file or the FIFO to obtain these credentials.
Additionally, the log file was not removed before creation, meaning a pre-existing symlink in /var/log could have been used to redirect the write to an arbitrary location.

fix: [security] Create the installer log and its FIFO | e0af51eb247c… |
Fix summary
The installer scripts now explicitly create the log file with 0600 permissions using install -m 0600 and the FIFO with mkfifo -m 0600, ensuring both are root-readable/writable only from the moment of creation. The log file is also removed (rm -f) before creation to prevent a pre-existing symlink in /var/log from being used to redirect the write to an attacker-controlled path. This matches the existing 0600 treatment applied to /root/misp_settings.txt by the save_settings() function.
Patch summary
In all four installer scripts (INSTALL.debian12.sh, INSTALL.debian13.sh, INSTALL.ubuntu2404.sh, xINSTALL.rhel94.sh), the single line mkfifo ${logfile}.pipe is replaced with three lines: rm -f "$logfile" to remove any pre-existing file or symlink; install -m 0600 /dev/null "$logfile" to create the log file with root-only permissions; and mkfifo -m 0600 ${logfile}.pipe to create the FIFO with root-only permissions. The subsequent tee and exec redirection lines remain unchanged.
CVSS rationale
Attack Vector is Local because the attacker must have a local account or shell access on the system where the MISP installer runs. Attack Complexity is Low because reading a world-readable file requires no special conditions. No Attack Target manipulation is needed. Privileges Required is None because the file is world-readable (0644) and any unprivileged local user can read it. No User Interaction is required. Confidentiality impact is High because the log contains the admin password, database passwords, GPG passphrase, and supervisor password, granting full compromise of the MISP deployment. Integrity and Availability impacts are None. Scope is Not Changed because the exposed credentials belong to the same MISP system. The vulnerability is transient (only during installation) but the log file persists after installation unless manually removed.
Weakness rationale
- CWE-732 The installer log file and FIFO were created under the default umask, resulting in world-readable permissions on a file containing sensitive credentials (admin password, database passwords, GPG passphrase, supervisor password). The fix explicitly sets 0600 permissions, confirming the root cause was incorrect permission assignment.
- CWE-22 The log file was not removed before creation, allowing a pre-existing symlink in /var/log to redirect the write to an arbitrary file. The fix adds rm -f before creation to mitigate this symlink-following risk. This is a secondary weakness addressed by the same patch.
Attack pattern rationale
- CAPEC-135 The most direct attack pattern is a local unprivileged user simply reading the world-readable log file at /var/log/misp_install.log to harvest sensitive credentials. No complex exploitation is required beyond file read access. CAPEC-135 covers the general pattern of an attacker leveraging misconfigured file permissions to access sensitive data. The symlink variant (CWE-22) could also map to CAPEC-135 as a sub-technique of permission exploitation.
Assumptions to verify
- The affected version range is inferred from the tag_version_boundary (v2.5.47 with 38 commits after fix); the exact first affected version is not specified in the patch metadata.
- The vulnerability is transient in the sense that it only manifests during the installer execution window, but the log file persists on disk after installation and remains world-readable unless the administrator manually changes permissions or removes it.
- The CVSS assumes the log file remains on disk after installation; if it is immediately removed by the installer, the exposure window is shorter but the file is still readable during the installation process.
- CAPEC-135 is the closest available attack pattern; no CAPEC specifically covers 'reading a world-readable log file containing credentials,' so the general permission-misuse pattern is the best match.
- The symlink attack vector (CWE-22) is a secondary concern addressed by the same patch; the primary vulnerability is the incorrect file permissions (CWE-732).
- The installer is assumed to run as root (standard for system installation scripts), which is why 0600 permissions restrict access to root only.

Mitigation
Implementation
When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user) [REF-62], and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
Mitigation
Architecture and Design
Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly. This will allow you to maintain more fine-grained control over your resources. [REF-207]
Mitigation MIT-22
Architecture and Design
Operation
Strategy: Sandbox or Jail
- Run the code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
- OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation
Implementation
Installation
During program startup, explicitly set the default permissions or umask to the most restrictive setting possible. Also set the appropriate permissions during program installation. This will prevent you from inheriting insecure permissions from any user who installs or runs the program.
Mitigation
System Configuration
For all configuration files, executables, and libraries, make sure that they are only readable and writable by the software's administrator.
Mitigation
Documentation
Do not suggest insecure configuration changes in documentation, especially if those configurations can extend to resources and other programs that are outside the scope of the application.
Mitigation
Installation
Do not assume that a system administrator will manually change the configuration to the settings that are recommended in the software's manual.
Mitigation MIT-37
Operation
System Configuration
Strategy: Environment Hardening
Ensure that the software runs properly under the United States Government Configuration Baseline (USGCB) [REF-199] or an equivalent hardening configuration guide, which many organizations use to limit the attack surface and potential risk of deployed software.
Mitigation
Implementation
System Configuration
Operation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to disable public access.
CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs
In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.
CAPEC-122: Privilege Abuse
An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
CAPEC-127: Directory Indexing
An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-180: Exploiting Incorrectly Configured Access Control Security Levels
An attacker exploits a weakness in the configuration of access controls and is able to bypass the intended protection that these measures guard against and thereby obtain unauthorized access to the system or network. Sensitive functionality should always be protected with access controls. However configuring all but the most trivial access control systems can be very complicated and there are many opportunities for mistakes. If an attacker can learn of incorrectly configured access security settings, they may be able to exploit this in an attack.
CAPEC-206: Signing Malicious Code
The adversary extracts credentials used for code signing from a production environment and then uses these credentials to sign malicious content with the developer's key. Many developers use signing keys to sign code or hashes of code. When users or applications verify the signatures are accurate they are led to believe that the code came from the owner of the signing key and that the code has not been modified since the signature was applied. If the adversary has extracted the signing credentials then they can use those credentials to sign their own code bundles. Users or tools that verify the signatures attached to the code will likely assume the code came from the legitimate developer and install or run the code, effectively allowing the adversary to execute arbitrary code on the victim's computer. This differs from CAPEC-673, because the adversary is performing the code signing.
CAPEC-234: Hijacking a privileged process
An adversary gains control of a process that is assigned elevated privileges in order to execute arbitrary code with those privileges. Some processes are assigned elevated privileges on an operating system, usually through association with a particular user, group, or role. If an attacker can hijack this process, they will be able to assume its level of privilege in order to execute their own code.
CAPEC-60: Reusing Session IDs (aka Session Replay)
This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
CAPEC-61: Session Fixation
The attacker induces a client to establish a session with the target software using a session identifier provided by the attacker. Once the user successfully authenticates to the target software, the attacker uses the (now privileged) session identifier in their own transactions. This attack leverages the fact that the target software either relies on client-generated session identifiers or maintains the same session identifiers after privilege elevation.
CAPEC-62: Cross Site Request Forgery
An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
CAPEC-642: Replace Binaries
Adversaries know that certain binaries will be regularly executed as part of normal processing. If these binaries are not protected with the appropriate file system permissions, it could be possible to replace them with malware. This malware might be executed at higher system permission levels. A variation of this pattern is to discover self-extracting installation packages that unpack binaries to directories with weak file permissions which it does not clean up appropriately. These binaries can be replaced by malware, which can then be executed.
