How to fix?

There is no fixed version for RHEL:7 rh-sso7-keycloak-server.

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 "Test Connection" available in v7.x of the Red Hat Single Sign On application console can permit an authorized user to cause SMTP connections to be attempted to arbitrary hosts and ports of the user's choosing, and originating from the RHSSO installation. By observing differences in the timings of these scans, an attacker may glean information about hosts and ports which they do not have access to scan directly.
