CVE-2026-40032 Details
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.
A command injection vulnerability has been identified in UAC (Unix-like Artifacts Collector) versions prior to 3.3.0-rc1. The vulnerability arises because the _run_command() function directly passes constructed command strings to eval without proper sanitization. This flaw allows attackers to inject shell metacharacters or command substitutions through controlled inputs, such as %line% values from foreach iterators and %user% / %user_home% values derived from system files. Exploitation of this vulnerability could lead to arbitrary command execution with the privileges of the UAC process.
Users can upgrade to UAC version 3.3.0-rc1 or later, where this vulnerability has been fixed.
