CVE-2026-41450

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.

Summary		(es) Las versiones de UAC (Unix-like Artifacts Collector) anteriores a la 3.3.0 contienen una vulnerabilidad de inyección de comandos en la función _command_collector donde las líneas de salida de cada comando se sustituyen directamente en cadenas de comandos a través de sed sin el escape adecuado antes de ser evaluadas con eval. Los atacantes pueden explotar esto creando nombres de archivo maliciosos o definiciones de artefactos que contengan metacaracteres de shell como sintaxis de sustitución de comandos o puntos y coma para ejecutar comandos arbitrarios en el sistema anfitrión del analista.
