Mambo Site Server may grant access without sufficiently validating cookie based authentication credentials. It has been reported that Mambo will accept a user cookie sent by the site as an administrative credential. To exploit this issue, the attacker must receive a cookie (such as the one issued during logout) and then use MD5 to encode their session ID in the cookie. The attacker may then access administrative pages using this cookie. This issue was reported in Mambo Site Server 4.0.12 RC2. Earlier versions may also be affected.
