pfSense: pfSense-SA-23_08.webgui: XSS vulnerability in the WebGUI
Description
A potential Cross-Site Scripting (XSS) vulnerability was found in getserviceproviders.php, a component of the pfSense Plus and pfSense CE software GUI. The page does not always validate or sanitize the value of the "connection" variable from user input, which then may be displayed without encoding. This problem is present on pfSense Plus version 23.05.1, pfSense CE version 2.7.0, and earlier versions of both. 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. The user must be logged in and have sufficient privileges to access getserviceproviders.php. The affected case requires a provider to only have one plan.
