Detailsinfo

A vulnerability was found in tclahr UAC up to 3.2.x. It has been declared as problematic. Affected by this vulnerability is the function _command_collector. The manipulation with an unknown input leads to a command injection vulnerability. The CWE definition for the vulnerability is CWE-77.

As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.
