Assigner: Checkmk GmbH

Description
Improper permission enforcement in Checkmk versions 2.4.0 before 2.4.0p21, 2.3.0 before 2.3.0p43, and 2.2.0 (EOL) allows users with the "Use WATO" permission to access the "Analyze configuration" page by directly navigating to its URL, bypassing the intended "Access analyze configuration" permission check. If these users also have the "Make changes, perform actions" permission, they can perform unauthorized actions such as disabling checks or acknowledging results.

Executive Summary

This vulnerability is an improper permission enforcement issue in certain versions of Checkmk (2.4.0 before 2.4.0p21, 2.3.0 before 2.3.0p43, and 2.2.0 which is end-of-life). It allows users who have the "Use WATO" permission to access the "Analyze configuration" page by directly navigating to its URL, bypassing the intended permission check for "Access analyze configuration."

Furthermore, if these users also have the "Make changes, perform actions" permission, they can perform unauthorized actions such as disabling checks or acknowledging results.

Impact Analysis

This vulnerability can impact you by allowing users with limited permissions to access and perform actions they are not authorized to do. Specifically, users with the "Use WATO" permission can bypass restrictions to access sensitive configuration analysis pages.

If these users also have the "Make changes, perform actions" permission, they could disable monitoring checks or acknowledge results without proper authorization, potentially leading to incorrect monitoring data, missed alerts, or unauthorized changes in the system.
