NVD Description

Note: Versions mentioned in the description apply only to the upstream eap7-jackson-databind package and not the eap7-jackson-databind package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

the Undertow AJP listener honours forged ssl_cert and is_ssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP protocol.
