Signature Validation Bypass

Impact An authentication bypass exists in the goxmldsig this library uses to determine if SAML assertions are genuine. An attacker could craft a SAML response that would appear to be valid but would not have been genuinely issued by the IDP. Patches Version 0.4.2 bumps the dependency which should...

UBUNTU-CVE-2020-5390

PySAML2 before 5.0.0 does not check that the signature in a SAML document is enveloped and thus signature wrapping is effective, i.e., it is affected by XML Signature Wrapping XSW. The signature information and the node/object that is signed can be in different places and thus the signature...

Type confusion

The XmlSecLibs library as used in the saml2 library in SimpleSAMLphp before 1.15.3 incorrectly verifies signatures on SAML assertions, allowing a remote attacker to construct a crafted SAML assertion on behalf of an Identity Provider that would pass as cryptographically valid, thereby allowing th...

CVE-2018-7644

CVE-2018-7644 affects SimpleSAMLphp prior to 1.15.3 where XmlSecLibs used by the saml2 library incorrectly verifies SAML assertions, enabling a remote attacker to craft an assertion from an Identity Provider that passes cryptographic checks and impersonate a user from that IdP. The issue is a key...

CVE-2015-5372

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...
