Authentication bypass in Four-Faith F3X36 firmware 2.0.0 allows remote attackers to gain administrative access via crafted HTTP requests. The administrative web server accepts embedded debug credentials on /Status_Router.asp instead of enforcing the configured administrator credentials. The management interface must be network-reachable, and successful use grants control to read status data and change router settings.
