How to fix?

There is no fixed version for RHEL:7 openshift4/ose-haproxy-router.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/ose-haproxy-router package and not the openshift4/ose-haproxy-router package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in the OpenShift Router. When a Route has insecureEdgeTerminationPolicy set to Allow, the HTTP frontend does not remove X-SSL-Client-* headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted X-SSL-Client-* headers. As a result, backends relying on these headers for mutual TLS (Transport Layer Security) authentication can be bypassed, enabling the attacker to impersonate client certificate identities.
