Title
Netgate pfSense CE 2.7.1 through 2.9.0 CRLF Injection via services_unbound_advanced.php
Summary
Netgate pfSense CE from 2.7.1 through 2.9.0 contains a CRLF injection vulnerability in services_unbound_advanced.php that allows authenticated users with DNS Resolver: Advanced privilege to inject Unbound directives. Attackers can embed CR/LF characters in the unvalidated sock_queue_timeout parameter, which is written raw into unbound.conf, to override local records and forwarding for all clients.

Title
Netgate pfSense CE through 2.9.0 php.ini Injection via Timezone Setting
Summary
Netgate pfSense CE through 2.9.0 contains a php.ini injection vulnerability that allows authenticated users with General Setup privileges to inject directives by submitting an unvalidated timezone value. Attackers can embed a quote and newline to add auto_prepend_file pointing at /var/db/zoneinfo, executing PHP as root after php.ini is regenerated at boot or php-fpm restart.

Title
Netgate pfSense CE through 2.9.0 Command Injection via RADIUS Secret mpd.conf Injection
Summary
Netgate pfSense CE through 2.9.0 contains a configuration injection vulnerability that allows authenticated WebGUI users to inject mpd5 commands by submitting an unescaped RADIUS shared secret. Attackers with L2TP or PPPoE Server edit privileges can POST a secret containing a quote and newline to vpn_l2tp.php or services_pppoe_edit.php, appending an up-script that executes as root when a session starts.

Title
Netgate pfSense CE through 2.9.0 Crontab Injection via PPP Periodic Reset ptpid
Summary
pfSense CE through 2.9.0 contains a crontab injection vulnerability in interfaces_ppps_edit.php that allows authenticated users to execute commands as root by injecting newlines into the ptpid or reset hour/minute fields. Attackers holding the 'WebCfg - Interfaces: PPPs: Edit' privilege can submit crafted POST values that configure_cron() writes unescaped into /etc/crontab, running arbitrary root commands on schedule.

Title
Netgate pfSense CE through 2.9.0 Command Injection via PPPoE Server Username
Summary
Netgate pfSense CE through 2.9.0 contains a newline injection vulnerability in services_pppoe_edit.php that allows privileged users to inject mpd.secret entries via unvalidated username POST fields. Attackers with the PPPoE Server Edit privilege can add a line whose secret begins with '!', making mpd5 run commands as root when a PPPoE client authenticates.

Title
FreeRDP 3.0.0 before 3.32.0 HTTP Header Injection via Proxy Routing Token
Summary
FreeRDP 3.0.0 before 3.32.0 allows HTTP header injection in its proxy because a lone LF in the target portion of a routing token (Cookie: msts=) is not rejected and is written by http_proxy_connect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a proxy using FixedTarget=false and an upstream HTTP proxy can alter HTTP request/header framing at that upstream proxy.

CVE-2026-102938 (GCVE-0-2026-102938)

Vulnerability from cvelistv5 – Published: 2026-09-29 20:58 – Updated: 2026-09-30 19:53
VLAI
Title
virtualenv writes prompt values into pyvenv.cfg without sanitizing line boundaries, allowing configuration injection
Summary
virtualenv is a tool for creating isolated virtual python environments. Prior to 21.7.11, PyEnvCfg.write() writes prompt values verbatim to the line-oriented pyvenv.cfg format while PyEnvCfg._read_values() parses the file with str.splitlines() and accepts the last value for duplicate keys. An attacker who influences --prompt, VIRTUALENV_PROMPT, or configuration input can insert a recognized line boundary and additional keys, including home, causing consumers to use an attacker-selected base interpreter or corrupted environment metadata. The security impact requires prompt input from outside the operator's trust boundary; directly supplied prompt content primarily corrupts the operator's own environment. This issue is fixed in version 21.7.11.

CVE-2026-102136 (GCVE-0-2026-102136)

Vulnerability from cvelistv5 – Published: 2026-09-30 20:12 – Updated: 2026-10-01 13:37
VLAI
Title
Kiteworks Core Command Execution through Configuration Injection
Summary
In multi-node deployments, an attacker who had already obtained code execution on one appliance node could submit a value through an internal cluster interface that was written into monitoring configuration on another node without sufficient validation, potentially allowing OS commands to be executed there. Execution was limited to an unprivileged service account on that node.

Mitigation
Implementation

Avoid using CRLF as a special sequence.

Mitigation
Implementation

Appropriately filter or quote CRLF sequences in user-controlled input.

CAPEC-15: Command Delimiters

An attack of this type exploits a programs' vulnerabilities that allows an attacker's commands to be concatenated onto a legitimate command with the intent of targeting other resources such as the file system or database. The system that uses a filter or denylist input validation, as opposed to allowlist validation is vulnerable to an attacker who predicts delimiters (or combinations of delimiters) not present in the filter or denylist. As with other injection attacks, the attacker uses the command delimiter payload as an entry point to tunnel through the application and activate additional attacks through SQL queries, shell commands, network scanning, and so on.

CAPEC-81: Web Server Logs Tampering

Web Logs Tampering attacks involve an attacker injecting, deleting or otherwise tampering with the contents of web logs typically for the purposes of masking other malicious behavior. Additionally, writing malicious data to log files may target jobs, filters, reports, and other agents that process the logs in an asynchronous attack pattern. This pattern of attack is similar to "Log Injection-Tampering-Forging" except that in this case, the attack is targeting the logs of the web server and not the application.
