Discussion

The Kubernetes etcd key-value store provides a way to store data to the Control Plane. If these files can be changed, data to API object and Control Plane would be compromised.

Check Content

Review the permissions of the Kubernetes etcd by using the command:

ls -AR /var/lib/etcd/*

If any of the files have permissions more permissive than "644", this is a finding.

Fix Text

Change the permissions of the manifest files to "644" by executing the command:

chmod -R 644 /var/lib/etcd/*
