ADN Forum Cookie Authentication Bypass Vulnerability

ADN Forum is prone to an authentication-bypass vulnerability because it fails to adequately verify user-supplied input used for cookie-based authentication.

An attacker can exploit this vulnerability to gain administrative access to the affected application; other attacks are also possible.

This issue affects ADN Forum 1.0b and prior versions.
