CVE-2017-11428 (GCVE-0-2017-11428)

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

Title

Multiple SAML libraries may allow authentication bypass via incorrect XML canonicalization and DOM traversal

Summary

OneLogin Ruby-SAML 1.6.0 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.

Severity

7.7 (High)
