Command Injection in UAC Prior to 3.3.0

Publication date: 2026-08-21

Last updated on: 2026-08-21

Assigner: VulnCheck

Description
UAC (Unix-like Artifacts Collector) versions prior to 3.3.0 contain a command injection vulnerability in the _run_command function that allows attackers to execute arbitrary commands by injecting shell metacharacters into untrusted data such as usernames, process names, or filenames. Attackers can exploit this vulnerability through crafted evidence inputs, mounted images with hostile filenames, or tampered artifact definitions to achieve remote code execution on the analyst's host when processing evidence.

Executive Summary

CVE-2026-41449 is a command injection vulnerability in UAC (Unix-like Artifacts Collector) versions before 3.3.0. It exists in the _run_command function where untrusted input like usernames, process names, or filenames can inject shell metacharacters. Attackers can craft evidence inputs or filenames to execute arbitrary commands on the analyst's system during evidence processing.

Detection Guidance

Check UAC version with uac --version. If version is below 3.3.0, the system is vulnerable. Review artifact configuration files for unquoted placeholders like %user%, %user_home%, or %line% in paths or commands.

Impact Analysis

If you use UAC versions prior to 3.3.0, an attacker could exploit this to run malicious commands on your system. This could lead to data theft, system compromise, or further network infiltration. The impact depends on the privileges of the UAC process and the attacker's goals.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's integrity and confidentiality requirements or HIPAA's security rules. Organizations using affected UAC versions may face compliance violations, fines, or reputational damage if exploited.

Mitigation Strategies

Upgrade UAC to version 3.3.0 or later. If upgrading is not possible, review and modify artifact configurations to ensure all placeholders are properly escaped or quoted. Avoid processing untrusted evidence inputs until patched.
