Traffic disclosure and alteration via disabled TLS verification
Published Feb 2, 2026 · Updated Feb 2, 2026
Improper certificate validation in Red Hat Satellite 6 allows man-in-the-middle attackers to read or alter OpenShift traffic. The foreman_kubevirt client sets kubevirt_verify_ssl to false whenever the CA field is blank instead of using the system trust store. Exploitation requires a configured OpenShift compute resource with no explicit CA and control of the network path between Satellite and OpenShift, which exposes bearer-token and API traffic to reading or modification.
