What is CVE-2025-67446?

The Neterbit NW-431F Router is susceptible to an authentication bypass vulnerability due to the use of weak and predictable cookie values for authentication. This misconfiguration allows attackers to manipulate the cookie by altering its value, such as changing it to 'admin', thus evading the authentication mechanism. Successful exploitation can lead to unauthorized access to sensitive administrative functionalities of the router, posing significant security risks for affected users.
