CVE-2018-7340 (GCVE-0-2018-7340)

Vulnerability from cvelistv5 – Published: 2019-04-17 14:01 – Updated: 2024-08-05 06:24

Summary

Duo Network Gateway 1.2.9 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)
