Command Injection in UAC Unix-like Artifacts Collector

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 _command_collector function where foreach command output lines are substituted directly into command strings via sed without proper escaping before being evaluated with eval. Attackers can exploit this by crafting malicious filenames or artifact definitions containing shell metacharacters such as command substitution syntax or semicolons to execute arbitrary commands on the analyst's host system.

Executive Summary

UAC versions before 3.3.0 have a command injection flaw in the _command_collector function. The issue occurs when command output lines are inserted into sed commands without proper escaping, then evaluated with eval. Attackers can exploit this by using malicious filenames or artifact definitions with shell metacharacters like semicolons or command substitution to run arbitrary commands on the analyst's system.

Detection Guidance

Check UAC version with 'uac --version' or inspect the command_collector.sh script for the vulnerable _command_collector function. Look for files or artifact definitions with shell metacharacters like semicolons or command substitution syntax.

Impact Analysis

If you use UAC versions prior to 3.3.0, an attacker could execute arbitrary commands on your system by tricking you into processing a malicious file or artifact definition. This could lead to data theft, system compromise, or further network infiltration depending on your system privileges.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR's integrity and confidentiality requirements or HIPAA's safeguards for protected health information. Organizations may face compliance violations, fines, or legal consequences if exploited.

Mitigation Strategies

Upgrade UAC to version 3.3.0 or later. If immediate upgrade is not possible, avoid using UAC with untrusted artifact definitions or filenames. Review and sanitize inputs to the command_collector.sh script.
