CVE-2026-14852: mk_sap_hana: Privilege escalation via crafted sapstartsrv process name

Noroxi assessment

Priority: Monitor (action score 20/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: Checkmk GmbH Checkmk 2.3.0p49, 2.4.0p34, 2.5.0p9.

Low priority for now. Upgrade to Checkmk GmbH Checkmk 2.3.0p49, 2.4.0p34, 2.5.0p9 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Privilege escalation in Checkmk versions 2.5.0 before 2.5.0p9, 2.4.0 before 2.4.0p34, 2.3.0 before 2.3.0p49, and 2.2.0 (EOL) allows a local unprivileged user to execute arbitrary commands as root by starting a process crafted to look like a SAP HANA instance. Without an explicit database configuration, the mk_sap_hana agent plugin derives instance identifiers from the process list and uses them to build a command executed with elevated privileges (requires the plugin to run as root with RUNAS=agent).
