Description Insufficient permission validation in Checkmk versions prior to 2.4.0p17 and 2.3.0p42 allow low-privileged users to view agent information via the REST API, which could lead to information disclosure.
A vulnerability exists in Checkmk versions prior to 2.4.0p17 and 2.3.0p42, where insufficient permission validation in the REST API allows low-privileged users to access agent information. This could lead to unauthorized information disclosure, including sensitive data such as agent configurations and associated secrets. The vulnerability affects the commercial editions of Checkmk in the default configuration.
Users can upgrade to Checkmk versions 2.4.0p17 or 2.3.0p42, both of which include the necessary permission fixes. Instructions for downloading these versions are available on the Checkmk website.
