Root command execution via forged process name
Published Jul 14, 2026 · Updated Jul 14, 2026
OS command injection in affected Checkmk Linux agents allows local users to execute arbitrary commands as root through a forged process name. Without explicit database configuration, mk_sap_hana derives an instance identifier from the process list and inserts it into a privileged command without strict validation. Exposure requires Checkmk 2.5.0 before 2.5.0p9, 2.4.0 before 2.4.0p34, 2.3.0 before 2.3.0p49, or 2.2.0, with process-list discovery and root execution under RUNAS=agent.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=2.2.0
- Affected versionversion=2.3.0 <2.3.0p49
- Affected versionversion=2.4.0 <2.4.0p34
- Affected versionversion=2.5.0 <2.5.0p9
