Guardian language-system passes the id GET parameter directly into a PHP exec() call in complex_start.php (line 14) without sanitization: exec(\"php jobs/complex.php \".$login_session.\" \".$_GET['id'].\" ...\"). No authentication is required. An unauthenticated remote attacker can append shell metacharacters to execute arbitrary OS commands on the server.
