Authentication Bypass in Zyxel Router Firmware by Remote Attackers

CVE-2008-1259

What is CVE-2008-1259?

The Zyxel P-2602HW-D1A router exhibits a vulnerability related to the management of authentication states based on IP addresses. This flaw enables remote attackers to exploit the authentication mechanism by impersonating a user who has recently logged in. If an attacker can establish a connection from an IP address that was previously authenticated within the last 5 minutes, they can bypass the security measures, potentially gaining unauthorized access to the router's features and settings. This vulnerability underscores the importance of robust session management and proper authentication mechanisms in network devices.
