Description

Privilege escalation in the mk_mysql agent plugin on Windows in Checkmk <2.4.0p29, <2.3.0p47, and 2.2.0 (EOL) allows a local unprivileged user able to create a Windows service whose name matches 'MySQL' or 'MariaDB' (or with write access to a binary referenced by such a service) to execute arbitrary code in the context of the Checkmk agent service, which typically runs as SYSTEM.
