CWEhttps://cwe.mitre.org/data/definitions/276.html

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.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
