A privilege escalation vulnerability exists in OpenShift Container Platform which allows for compromise of pods running co-located on a compute node. This access could include access to all secrets, pods, environment variables, running pod/container processes, and persistent volumes, including in privileged containers.
Find out more about CVE-2018-1002105 from the MITRE CVE dictionary dictionary and NIST NVD.
In versions 3.6 and higher of OpenShift Container Platform, this vulnerability allows cluster-admin level access to any API hosted by an aggregated API server. This includes the ‘service catalog’ API which is installed by default in 3.7 and later. Cluster-admin level access to the service catalog allows creation of brokered services by an unauthenticated user with escalated privileges in any namespace and on any node. This could lead to an attacker being allowed to deploy malicious code, or alter existing services.
