In Red Hat Openshift 1, weak default permissions are applied to the /etc/openshift/server_priv.pem file on the broker server, which could allow users with local access to the broker to read this file.

Security readout for executives and security teams

Plain-English summary

CVE-2013-4281 affects Red Hat OpenShift 1 broker servers. A private server key file was created with weak default permissions, so a user who already has local access to the broker could read it. The main business risk is confidentiality loss, not remote takeover.

Executive priority

Treat this as a moderate legacy-platform risk. It is not described as remotely exploitable, but private key exposure can undermine trust boundaries. Prioritize systems with shared local access, untrusted operators, or compliance-sensitive workloads.

Technical view

The issue is CWE-276: incorrect default permissions on /etc/openshift/server_priv.pem. The CVSS v3.1 vector is local, low complexity, low privileges, no user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact.

Likely exposure

Exposure is likely limited to Red Hat OpenShift 1 broker servers where local users or processes can access the broker host. Organizations not running this legacy OpenShift version are not indicated as affected by the supplied sources.

Exploitation context

The source bundle does not cite public exploitation, and CISA KEV is false. Abuse requires local access to the broker server and depends on the weak file permissions being present. No remote attack path is described in the supplied evidence.

Researcher notes

Evidence is narrow and points to a local confidentiality issue caused by weak default permissions. The supplied bundle identifies Red Hat OpenShift 1 only. Do not broaden affected versions without vendor confirmation.

Mitigation direction

  • Check Red Hat/OpenShift security guidance for the supported corrective action.
  • Review and harden permissions and ownership per vendor guidance.
  • Restrict broker host access to trusted administrators only.
  • Rotate affected private keys if unauthorized local access is suspected.
  • Plan retirement or isolation of legacy OpenShift 1 deployments.

Validation and detection

  • Inventory environments for Red Hat OpenShift 1 broker servers.
  • Verify /etc/openshift/server_priv.pem permissions against vendor guidance.
  • Review local users and service accounts with broker host access.
  • Check audit logs for unexpected reads of the private key file.
  • Confirm no newer supported platform replaced this broker role.

Incorrect Default Permissions

Incorrect Default Permissions represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
