CVE-2022-33912: Checkmk

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

A permission issue affects users that deployed the shipped version of the Checkmk Debian package. Packages created by the agent bakery (enterprise editions only) were not affected. Using the shipped version of the agents, the maintainer scripts located at /var/lib/dpkg/info/ will be owned by the user and the group with ID 1001. If such a user exists on the system, they can change the content of these files (which are then executed by root). This leads to a local privilege escalation on the monitored host. Version 1.6 through 1.6.9p29, version 2.0 through 2.0.0p26, version 2.1 through 2.1.0p3, and version 2.2.0i1 are affected.

Affected products

• Checkmk Checkmk: version 1.6.0 only; version 2.0.0 only; version 2.1.0 only; version 2.2.0 only
• TRIBE29 Checkmk: version 1.6.0b10 only; version 1.6.0b11 only
