UAC (Unix-like Artifacts Collector) versions prior to 3.3.0 contain a command injection vulnerability in the user substitution logic within parse_artifact.sh where usernames and home directories from /etc/passwd are substituted directly into command strings without escaping before execution via eval. Attackers can inject shell metacharacters such as command substitution syntax or semicolons through crafted usernames or home directory paths in /etc/passwd entries 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 parse_artifact.sh script. The flaw exists in the user substitution logic where usernames and home directories read from /etc/passwd are directly interpolated into command strings without proper escaping before being executed via eval. An attacker who can control /etc/passwd entries (e.g., on a compromised host being analyzed) can craft malicious usernames or home directory paths containing shell metacharacters such as command substitution syntax or semicolons. When an analyst runs UAC against such a system, the injected commands execute on the analyst's own host system. This represents a significant risk to forensic investigators and incident responders using UAC. The vulnerability has been patched in UAC version 3.3.0.
