Detailed vulnerability description
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to incorrect default permissions for files and folders that are set by the application during installation of an OpenShift 4 cluster. The `openshift-install` command line tool creates an `auth` directory, with `kubeconfig` and `kubeadmin-password` files. Both files contain credentials used to authenticate to the OpenShift API server, and are incorrectly assigned word-readable permissions.
