Summary

An improper authorization vulnerability in the Plesk XML API allows an authenticated user to inject arbitrary configuration directives, resulting in arbitrary file write as root and full privilege escalation on the underlying server. A flaw was found in Plesk.

Although the go-acme/lego dependency is present, Red Hat OpenShift Dev Spaces does not ship or use the affected Plesk functionality. Therefore, the vulnerable code path is not exposed in this product.

Red Hat severity: Important — CVSS 9.9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). Weakness: CWE-15.

Mitigation checklist

Recommended fix / mitigation
  • Red Hat OpenShift Dev Spaces is not affected because it does not ship or rely on Plesk or expose the Plesk XML API. The vulnerable functionality resides within the Plesk-specific integration of the go-acme/lego library, which is not used by the product. Authentication is also required to exploit the vulnerability. No product changes are required.
