Name of the Vulnerable Software and Affected Versions
OpenShift Router (affected versions not specified)
Description
A flaw in the HTTP frontend occurs when a Route has the
insecureEdgeTerminationPolicy set to Allow. In this configuration, the router fails to remove X-SSL-Client-* headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests containing crafted X-SSL-Client-* headers. Consequently, backends that rely on these headers for mutual TLS (Transport Layer Security)—a process where both the client and server authenticate each other via certificates—can be bypassed, allowing the attacker to impersonate client certificate identities.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
