CVSS v3.1

7.8

HIGH

Description

UAC (Unix-like Artifacts Collector) before 3.3.0-rc1 contains a command injection vulnerability in the placeholder substitution and command execution pipeline where the _run_command() function passes constructed command strings directly to eval without proper sanitization. Attackers can inject shell metacharacters or command substitutions through attacker-controlled inputs including %line% values from foreach iterators and %user% / %user_home% values derived from system files to achieve arbitrary command execution with the privileges of the UAC process.
