How to fix?

Upgrade RHEL:7 rh-sso7-keycloak-server to version 0:18.0.7-1.redhat_00001.1.el7sso or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rh-sso7-keycloak-server package and not the rh-sso7-keycloak-server package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
