Descriptions
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.
OmniAuth OmnitAuth-SAML versión 1.9.0 y versiones anteriores pueden utilizar incorrectamente los resultados de las API de transversalización y canonicalización de DOM de XML de tal manera que un atacante pueda manipular los datos de SAML sin invalidar la firma criptográfica, lo que permite que el ataque omita la identificación de los proveedores de servicio SAML.
