Description
A Cross-Site Scripting (XSS) vulnerability was found in pkg.php, a component of
the pfSense Plus and pfSense CE software GUI. This problems is present on
pfSense Plus version 21.05.2, pfSense CE version 2.5.2, and earlier versions of
both.
The page did not sanitize the contents of the pkg_filter parameter nor did it
encode the output when it included the value of that parameter in the page,
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.
