Information Disclosure

Description

Insufficient permission validation on multiple REST API Quick Setup endpoints in Checkmk 2.5.0 (beta) before version 2.5.0b2 and 2.4.0 before version 2.4.0p25 allows low-privileged users to perform unauthorized actions or obtain sensitive information

Analysis

Insufficient permission validation in Checkmk REST API Quick Setup endpoints allows low-privileged authenticated users to perform unauthorized administrative actions or access sensitive information in versions 2.5.0 beta before 2.5.0b2 and 2.4.0 before 2.4.0p25. The vulnerability stems from missing authorization checks that fail to enforce role-based access control on multiple API endpoints, enabling privilege escalation within the monitoring platform.
