Comodo Dome Firewall Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in Comodo Dome Firewall version 2.7.0. This vulnerability allows unauthenticated attackers to inject malicious scripts by submitting crafted input to the username parameter. Attackers can exploit this by sending POST requests to the login endpoint with script payloads in the username field, which then execute arbitrary JavaScript in the browsers of users.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where injected scripts are executed in the context of the user's browser.

Reproduction

To reproduce this vulnerability, send a POST request to the login endpoint with a script payload in the username parameter. The injected script will be executed in the user's browser, demonstrating the cross-site scripting vulnerability.
