CVE-2017-11427 (GCVE-0-2017-11427)

Vulnerability from cvelistv5 – Published: 2019-04-17 13:59 – Updated: 2024-08-05 18:12

Summary

OneLogin PythonSAML 2.3.0 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.
