Description

A Cross-Site Scripting (XSS) vulnerability was found in status_filter_reload.php, a page in the pfSense software WebGUI, on version 2.4.4-p2 and earlier. The page did not encode output from the filter reload process, and a stored XSS was possible via the descr (description) parameter on NAT rules. Due to the lack of proper encoding on the affected parameters susceptible to XSS, arbitrary JavaScript could be executed in the user's browser. The user's session cookie or other information from the session may be compromised.
