UAC vulnerabilities

UAC before version 3.3.0 has a command injection vulnerability in the user substitution logic in parse_artifact.sh. Usernames and home directories from /etc/passwd are substituted into command strings without proper escaping before execution via eval, allowing injection of shell metacharacters.

UAC before version 3.3.0 has a command injection vulnerability in the _command_collector function, where foreach command output lines are substituted into command strings via sed without proper escaping before being evaluated with eval. Attackers can exploit malicious filenames or artifact definitions.

UAC before version 3.3.0 has 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.

UAC (Unix-like Artifacts Collector) before version 3.3.0-rc1 contains a command injection vulnerability in the placeholder substitution and command execution pipeline. The _run_command() function passes constructed command strings directly to eval without proper sanitization, allowing attackers to inject shell metacharacters through attacker-controlled inputs such as %line% values from foreach iterators and %user%/%user_home% values derived from system files.
