Name of the Vulnerable Software and Affected Versions pfSense versions prior to 2.3

Description The issue allows remote authenticated users to execute arbitrary OS commands. This is achieved by including a '|' character in the graph parameter of the status rrd graph img.php file, which is related to rrd graph img.php.

Recommendations For versions prior to 2.3, update to version 2.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the status rrd graph img.php file to minimize the risk of exploitation. Avoid using the '|' character in the graph parameter until the issue is resolved.
