Name of the Vulnerable Software and Affected Versions Guardian language-system (affected versions not specified)

Description An unauthenticated remote attacker can execute arbitrary OS commands on the server. The issue occurs because the application passes the id GET parameter directly into a PHP exec() function within the complex start.php file without proper sanitization. This allows the injection of shell metacharacters to trigger command execution.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
