GSD-2017-11430
Vulnerability from gsd - Updated: 2018-02-27 00:00Details
OmniAuth OmnitAuth-SAML 1.9.0 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.
