Duo Network Gateway 1.2.9 and earlier may incorrectly utilize the results of XML DOM traversal and canonicalization APIs in such a way that an attacker may be able to manipulate the SAML data without invalidating the cryptographic signature, allowing the attack to potentially bypass authentication to SAML service providers.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
