Description

Improper Authentication (Authentication Bypass) exists in Neterbit NW-431F Router 20241014-IR03 and before. The router uses a weak/predictable cookie value for authentication. By modifying the cookie value (e.g., setting it to "admin"), an attacker can bypass the authentication schema and gain unauthorized access to admin functionalities.
