Tenda AC7 Improper Output Encoding Vulnerability Allowing Cross-Site Scripting

A reflected cross-site scripting vulnerability has been identified in the Tenda AC7 router, specifically in firmware versions through V03.03.03.01_cn. This vulnerability arises from improper output encoding in the web management interface, where user-supplied input is reflected in HTTP responses without sufficient escaping. This flaw enables the injection of arbitrary HTML or JavaScript that is executed in the context of the victim's browser.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject malicious scripts that are executed in the context of the user's browser.
