Authentication bypass vulnerability in mod_nss 1.0.8 allows remote attackers to assume the identity of a valid user by using their certificate and entering password as the password.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
