Detail
Vulnerability Note VU#475445Multiple SAML libraries may allow authentication bypass via incorrect XML canonicalization and DOM traversalOverviewMultiple SAML libraries 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.
