Title
Four-Faith F3x36 bapply.cgi Auth Bypass
Summary
The Four-Faith F3x36 router using firmware v2.0.0 is vulnerable to an authentication bypass vulnerability in the administrative web server. Authentication is not enforced on some administrative functionality when using the "bapply.cgi" endpoint instead of the normal "apply.cgi" endpoint. A remote and unauthenticated can use this vulnerability to modify settings or chain with existing authenticated vulnerabilities.
