CWE-ID: CWE-276

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Red Hat OpenShift Container Platform
Client/Desktop applications / Software for system administration

Vendor: Red Hat Inc.

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.

Mitigation
Install updates from vendor's website.

Vulnerable software versions

Red Hat OpenShift Container Platform: 4.2.0 - 4.2.16
