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

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).

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

EPSS FIRST

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
