Reflected XSS In /index.cgi Endpoint On IDC Satellite Receiver Web Management Interface Version 101

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the /index.cgi endpoint of International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web Management Interface version 101. The application fails to adequately sanitize user-supplied input provided via the cat parameter before reflecting it in the HTTP response, allowing a remote attacker to execute arbitrary HTML or JavaScript in the victim's browser context.
