[2.2.0] Checkmk Werk 16159 deleted: linux-bonding: introduce check for expected bonding mode

by Checkmk werks level 1

Werk 16159 was deleted. The following Werk is no longer relevant. Title: linux-bonding: introduce check for expected bonding mode Class: feature Compatible: incomp Component: checks Date: 1698999268 Edition: cre Level: 1 Version: 2.2.0p17 The service monitoring rule "Linux monitoring service status" was previously being used for both Linux and OVS. This werk now splits this rule in two. We now have the following rules. Bonding interface status OVS bonding interface status The reason behind this, is that we have now introduced an expected mode configuration parameter only for the Linux rule. So you are now able to select the expected bonding mode and the state you want to display when this condition is not met. Actions: Case 1: Rule configured for linux Action: do nothing. Case 2: Rule configured for OVS Action: All previously configured rules will now appear as Linux Bonding interface status rules. Therefore you will have to delete them and create new "OVS Bonding interface status" rules.

[2.2.0] Checkmk Werk 16226 created: Privilege escalation in Agent

by Checkmk werks level 1

Title: Privilege escalation in Agent Class: security Compatible: compat Component: checks Date: 1701938773 Edition: cre Level: 2 Version: 2.2.0p17 In order to monitor livestatus from running sites on a host the Checkmk agent uses unixcat that is part of Checkmk. Since the binary is linked to libraries that are also part of Checkmk and may differ from the libraries of the operating system calling unixcat outside of the scope of a site could result to errors due to version mismatches in these libraries. To use the correct libraries in Checkmk 2.2.0p10 a fix was introduced to add the libraries from the site to the call in the agent. Since the lib folder within a site is writable by the site a rogue site could inject malicious libraries into the unixcat call from the agent that is executed as root leading to a privilege escalation. We thank Jan-Philipp Litza for reporting this issue. Affected Versions: * since 2.2.0p10 Vulnerability Management: We have rated the issue with a CVSS Score of 8.8 (High) with the following CVSS vector: <tt>CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H</tt>. We assigned CVE-2023-31210 to this vulnerability. Changes: This Werk changes the library path from the site to the version files, which are only root-writable.
