Description
A Cross-Site Scripting (XSS) vulnerability was found in diag_dns.php, a part of
the pfSense software WebGUI, on version 2.3.4 and earlier (2.3.x branch) and on
version 2.4.1 and earlier (2.4.x branch).
On diag_dns.php, the "hostname" parameter was being utilized without encoding in
a JavaScript variable which could be used as an XSS vector.
Due to the lack of proper encoding on the affected variable susceptible to XSS,
arbitrary JavaScript can be executed in the user's browser. The user's session
cookie or other information from the session may be compromised.
