Checkmk Werk 13680: Agent Bakery: Make package compression optional

by Andreas Umbreit

ID: 13680 Title: Agent Bakery: Make package compression optional Component: agents Level: 1 Class: New feature Version: 2.2.0i1 Compression of baked agent packages is now turned off by default. Recently, all agent packages got packaged with default compression options of the respective packaging system. This resulted in a gzip-level-9-compression of <tt>.rpm</tt>, <tt>.deb</tt>, and <tt>.tar.gz</tt> packages. However, as all large files (larger than a few kb) that are shipped with Checkmk are already precompressed, the influence to the package size was minimal, while there was a noticeable impact to the baking performance. Hence, the gzip compression is now deactivated by default (level set to 0), while you can activate it with the agent ruleset "Agent bakery package compression"

Checkmk Werk 14089: Checkmk agent TLS encryption and compression

by Moritz Kiemer

ID: 14089 Title: Checkmk agent TLS encryption and compression Component: Checks & agents Level: 2 Class: New feature Version: 2.2.0i1 In Checkmk version 2.1 the monitoring data sent from the monitored host to the monitoring server is TLS encrypted and compressed by default. This is realized by a new component on the monitored hosts: The Checkmk agent controller <tt>cmk-agent-ctl</tt>. The added executable is called <tt>cmk-agent-ctl</tt>. On Linux systems, the agent controller will be run as a dedicated user <i>cmk-agent</i>, which is added during installation. As a result the process listening on the TCP port will have limited privileges, and the agent output is not available to any other local user. While upgraded setups will continue to work as before, in order to enable TLS encryption an additional registration step is required. More information on the registration step, the installation and the provided commands can be found <a href="https://docs.checkmk.com/master/en/agent_linux.html">in our online documentation</a>.

Checkmk Werk 13902: Secure path for OMD hooks

by Maximilian Wirtz

ID: 13902 Title: Secure path for OMD hooks Component: OMD Level: 1 Class: Security fix Version: 2.2.0i1 OMD executes several hooks to determine configuration options (e.g. which port to use for the site apache). These hooks are version dependent, so OMD executed these hooks via a symlink in the site to get the hooks matching the version of the site. The symlinks belong to the site user in order to be able to update the version. Since a <i>OMD status</i> executes those hooks as root, it was possible for a site user to create a malicious hook and execute code as root. All maintained versions (>=1.6) are subject to this vulnerability. It is likely that also previous versions were vulnerable. CVE will be added later here. CVSS: CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H 8.2 We thank Timo Klecker for reporting this issue!
