CVE-2026-14852: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Checkmk GmbH Checkmk
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).
AI Analysis
Technical Summary
CVE-2026-14852 is an OS command injection vulnerability (CWE-78) in Checkmk's mk_sap_hana agent plugin. The plugin, when running as root with RUNAS=agent and without explicit database configuration, derives SAP HANA instance identifiers from the process list. An attacker can craft a process to appear as a SAP HANA instance, causing the plugin to execute arbitrary commands with root privileges, resulting in local privilege escalation. This affects Checkmk versions 2.5.0 prior to 2.5.0p9, 2.4.0 prior to 2.4.0p34, 2.3.0 prior to 2.3.0p49, and 2.2.0 (end-of-life).
Potential Impact
A local unprivileged user can escalate privileges to root by exploiting this vulnerability, potentially gaining full control over the affected system. The vulnerability requires local access and the mk_sap_hana plugin running as root with RUNAS=agent. There are no known exploits in the wild as of the publication date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the affected versions are prior to specific patch releases (2.5.0p9, 2.4.0p34, 2.3.0p49), upgrading to these patched versions or later is recommended once official patches are available. Until then, consider disabling the mk_sap_hana agent plugin or running it without elevated privileges if possible.
