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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
