Summary

An Improper Privilege Management vulnerability in SUSE Rancher allowed standard users to leverage existing permissions to manipulate Kubernetes secrets in the local cluster, resulting in the secret being deleted while read-level permissions were preserved. Followed by specially crafted commands, this could let a user gain access to tokens belonging to service accounts in the local cluster. Affects Rancher >= 2.6.0 < 2.6.13 and >= 2.7.0 < 2.7.4.

Risk Assessment

A standard user could escalate privileges and obtain service account tokens, potentially leading to takeover of the Kubernetes cluster.

Recommendation

Update Rancher to 2.6.13 or later, or 2.7.4 or later. Review user permissions and audit secret access.
