CVE-2022-46302

Root code execution via site-controlled Apache configuration

Published Apr 20, 2023 · Updated Feb 4, 2025

Affected Checkmk 1.6.0, 2.0.0, and 2.1.0 patch releases allow local site users to execute code as root through Apache configuration. The system Apache reads reverse-proxy configuration supplied by a less-privileged Checkmk site user without separating root-managed directives. An attacker must control a local site account; successful abuse grants root-level code execution and full control of the underlying host.
