Summary

A vulnerability in the TP-Link Archer C20 router allows unauthorized users to bypass the authentication mechanism for certain interfaces under the /cgi directory. When a specific HTTP Referer header is set to http://tplinkwifi.net, the request is erroneously treated as authenticated, enabling potential unauthorized access to sensitive router settings. This flaw poses a significant risk, particularly for users who may not be aware of the exposed interfaces and their implications.
