general/login.php en phpCollab 2.5 rc3 y anteriores, permiten a atacantes remotos ejecutar comandos arbitrarios a través de metacaracteres shell en entradas no específicas, relacionadas con la variable de entorno SSL_CLIENT_CERT. NOTA, en algunos entornos, SSL_CLIENT_CERT siempre tiene valor de cadena codificado en base 64, lo cual impone limitaciones a la inyección para shells típicas.
