- Severity: CVSS 6.0 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2.3.0p25, 2.2.0p39
- Published: 2025-04-10 · Updated: 2025-04-10

## Affected

- Checkmk GmbH Checkmk: from 2.3.0, fixed in 2.3.0p25; from 2.2.0, fixed in 2.2.0p39; from 2.1.0, through 2.1.0p50

## Description

Improper neutralization of livestatus command delimiters in a specific endpoint within RestAPI of Checkmk prior to 2.2.0p39, 2.3.0p25, and 2.1.0p51 (EOL) allows arbitrary livestatus command execution. Exploitation requires the attacker to have a contact group assigned to their user account and for an event to originate from a host with the same contact group or from an event generated with an unknown host.
