CVE-2022-40723Network attack vector

MFA bypass via missing LDAP group attributes

Published Apr 25, 2023 · Updated Feb 4, 2025

Authentication bypass in PingID RADIUS PCV allows remote authenticated users to complete RADIUS login without PingID MFA. The adapter fails to populate LDAP group attributes correctly, so affected group-based configurations make the wrong MFA enforcement decision. A valid primary credential and an affected group-based configuration are required; successful exploitation grants access without the second factor.
