The SAML 2.0 implementation in AdNovum nevisAuth 4.13.0.0 before 4.18.3.1, when using SAML POST-Binding, does not match all attributes of the X.509 certificate embedded in the assertion against the certificate from the identity provider (IdP), which allows remote attackers to inject arbitrary SAML assertions via a crafted certificate.
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
