Affected product context indicates that deployments using the PHP built-in server or certain non-default Nginx configurations are impacted.

Defensive priority

High

Recommended defensive actions

  • Apply the vendor patch or upgrade to a version of Cockpit CMS that is not vulnerable
  • Implement input validation and sanitization to prevent path traversal and local file inclusion attacks
  • Use a web application firewall to detect and prevent attacks
  • Monitor for suspicious activity and implement incident response plans
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
