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.

UAC (Unix-like Artifacts Collector) versions prior to 3.3.0 contain a command injection vulnerability in the _command_collector function. The flaw arises because foreach command output lines are substituted directly into command strings via sed without proper escaping, and then evaluated using eval. Attackers can exploit this by crafting malicious filenames or artifact definitions containing shell metacharacters such as command substitution syntax or semicolons. Successful exploitation allows arbitrary command execution on the analyst's host system. The vulnerability is particularly concerning as it targets forensic analysts who use UAC for incident response and artifact collection. A fix was introduced in UAC version 3.3.0. The patch is available via a GitHub commit and pull request. Security advisory details are also published by VulnCheck.
