Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of kubernetes installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-5408 advisory.

 - A privilege escalation flaw was found in the node restriction admission plugin of the kubernetes api server of OpenShift. A remote attacker who modifies the node role label could steer workloads from the control plane and etcd nodes onto different worker nodes and gain broader access to the cluster.
