CVE-2013-4281

Private-key disclosure via weak default file permissions

Published Oct 19, 2022 · Updated May 9, 2025

Incorrect default permissions in Red Hat OpenShift 1 allow local users on a broker server to read its private server key. The installer generates /etc/openshift/server_priv.pem but applies no restrictive file mode, leaving the private key readable through inherited defaults. Exploitation requires local broker access and exposes the private key; no write access or service interruption is reported.
