Description OSIDB Bzimport 2026-01-28 12:52:16 UTC
Summary: MITM in foreman_kubevirt due to insecure defaults

Requirements to exploit: Being able to MITM traffic between Satellite
and OpenShift

Component affected: https://github.com/theforeman/foreman_kubevirt

Version affected: <= 0.4.0

Patch available: no

Version fixed (if any already): N/A

CVSS (optional): N/A

Impact (optional): Important

Embargo: No

Reason: The amount of affected systems should be low
Suggested public date: dd-MMM-yyyy

Acknowledgement: Evgeni Golov

Steps to reproduce if available:

Configure OpenShift Virtualization / KubeVirt in Satellite and don't
enter anything in the CA field
Mitigation if available: Explicitly set a CA

Original report: this email

When foreman_kubevirt configures the connection to OpenShift, it only
enables `kubevirt_verify_ssl` when a CA certificate was explicitly set
in the settings [1].
Normally, users would expect that the system trust store is used when
no explicit CA was set.
But in this case the whole verification is disabled instead.
