Short explanation
Incorrect permissions on the Checkmk Windows agent's data directory, caused by a race condition that discards permission changes during service start, allow a local user to execute arbitrary code as SYSTEM by placing scripts in agent folders and reading the agent controller's private key in Checkmk <2.5.0p18, <2.4.0p39, <2.3.0p52 and 2.2.0 (EOL) [S0].
This vulnerability allows local users to gain SYSTEM privileges and access sensitive key data, compromising the security of the targeted system [S0].
What should be done?
- Follow the official vendor advisory [S0].
- Apply updates for affected versions [S0].
- Review agent directory permissions and configurations [S0].
