Category:Privilege escalation
Title:Checkmk < 1.6.0p29, 2.0.x < 2.0.0p26, 2.1.x < 2.1.0p3 Privilege Escalation Vulnerability
Summary:Checkmk is prone to a privilege escalation vulnerability.
Description:Summary:
Checkmk is prone to a privilege escalation vulnerability.

Vulnerability Insight:
Wrong file ownership of the maintainer scripts located at
/var/lib/dpkg/info: they were owned by the user and group with the ID 1001 instead of root.
If such a user exists on your system, they can change the content of these files which are later
executed by root (during package installation, update or removal), leading to a local privilege
escalation on the monitored host.

Affected Software/OS:
Checkmk installations done via the Debian packages,
versions prior to 1.6.0p29, 2.0.x prior to 2.0.0p26 and 2.1.x prior to 2.1.0p3.

Solution:
See the referenced vendor advisory for steps how to check the
correct file permissions.
