Executive Summary

This vulnerability is a Reflected Cross-Site Scripting (XSS) issue found in the /index.cgi endpoint of the International Datacasting Corporation (IDC) SFX Series SuperFlex Satellite Receiver Web Management Interface version 101.

The problem occurs because the application does not properly sanitize user input provided via the 'cat' parameter before reflecting it back in the HTTP response.

As a result, a remote attacker can inject and execute arbitrary HTML or JavaScript code in the victim's browser, potentially leading to malicious actions within the context of the affected web interface.

Impact Analysis

This vulnerability can allow a remote attacker to execute arbitrary HTML or JavaScript code in the context of the victim's browser when they access the vulnerable web interface.

Such execution can lead to various impacts including theft of sensitive information, session hijacking, or performing actions on behalf of the victim without their consent.

Because the vulnerability requires user interaction (UI:A), the attacker typically needs to trick the victim into clicking a malicious link or visiting a crafted webpage.
