Description

A Cross-Site Scripting (XSS) vulnerability was found in diag_ping.php, a component of the pfSense software WebGUI, on version 2.4.4-p3 and earlier. The page did not validate the contents of the host parameter nor did it encode the output which could have included this value, leading to a possible XSS. 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.
