Summary
Guardian language-system passes the id GET parameter directly into a PHP exec() call in transcribe.php (line 15) without sanitization: exec(\"php jobs/transcribe.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.
