[2.2.0] Checkmk Werk 16080 created: mssql_datafiles/transactionlogs: Regression in maximum size calculation

by Checkmk werks level 1

Title: mssql_datafiles/transactionlogs: Regression in maximum size calculation Class: fix Compatible: compat Component: checks Date: 1694589964 Edition: cre Level: 1 Version: 2.2.0p25 This is a follow-up to Werk #14421. Since Checkmk 2.1.0p5, we calculate the maximum size as the sum of available and used size for unlimited instances. However, in some cases, we accidentally drop explicit thresholds for the maximum size if avaiable, falling back to the unlimited case.

[2.4.0] Checkmk Werk 15515 adapted: check_http: Soft deprecatation of old HTTP monitoring plug-in

by Checkmk werks level 1

Werk 15515 was adapted. The following is the new Werk, a diff is shown at the end of the message. [//]: # (werk v2) # check_http: Soft deprecatation of old HTTP monitoring plug-in key | value ---------- | --- date | 2024-04-03T13:15:48+00:00 version | 2.4.0b1 class | feature edition | cre component | checks level | 2 compatible | no The old plug-in is being deprecated in a soft way with this werk. Unlike hard deprecation, the deprecated rule set "Check HTTP service" will remain fully functional. However, new rules should only be created if absolutely necessary, such as when experiencing issues with the new "Check HTTP web service" implementation and needing to roll back to the old one. Please note that the rule set will be hard deprecated in version 2.4.0, meaning that you will no longer be able to create new rules. However, the plug-in itself will remain available as this is a component of the monitoring-plugins collection that comes with Checkmk. Please let us know if you find any features that were present in the old plug-in but are missing in the new one. ------------------------------------<diff>------------------------------------------- [//]: # (werk v2) # check_http: Soft deprecatation of old HTTP monitoring plug-in key | value ---------- | --- date | 2024-04-03T13:15:48+00:00 version | 2.4.0b1 class | feature edition | cre component | checks level | 2 compatible | no The old plug-in is being deprecated in a soft way with this werk.

by Checkmk werks level 1

Title: Disallow python_plugins and lnx_remote_alert_handlers agent config options for users without the "add_or_modify_executables" permission Class: fix Compatible: compat Component: wato Date: 1710499061 Edition: cre Level: 1 Version: 2.2.0p25 Without the "add_or_modify_executables" permission users do not have the right to change any executable run by checkmk, either on the site or via the agent. The agent config options "python_plugins" and "lnx_remote_alert_handlers" have not yet checked for that permission. In the UI "python_plugins" and "lnx_remote_alert_handlers are called "Python agent plugin execution (UNIX)" and "Remote alert handler (Linux)" respectively.

[2.4.0] Checkmk Werk 16665 created: Crash when accessing overridden built-in dashboard

by Checkmk werks level 1

[//]: # (werk v2) # Crash when accessing overridden built-in dashboard key | value ---------- | --- date | 2024-04-03T12:32:28+00:00 version | 2.4.0b1 class | fix edition | cre component | multisite level | 1 compatible | yes Accessing a built-in dashboard after overriding it with a custom dashboard could cause certain dashlets to crash. For example, you could access the built-in dashboard by clicking the link in Customize > Dashboards > Built-in. Another way to access the built-in dashboard is for example by having a bookmark to it. Now this crash no longer occurs and all dashlets render correctly.

[2.4.0] Checkmk Werk 16615 created: Remove websphere_mq plugin

by Checkmk werks level 1

[//]: # (werk v2) # Remove websphere_mq plugin key | value ---------- | --- date | 2024-03-11T11:09:48+00:00 version | 2.4.0b1 class | security edition | cre component | checks level | 1 compatible | yes With this Werk the `websphere_mq` plugin is removed for security reasons. In this plugin the output of `ps` is used to determine an argument for `runmqsc`. This meant that anybody who can launch processes with an arbitrary command line could manipulate one argument to `runmqsc`. The plugin was already superseded by the agent plugin `ibm_mq` and deprecated with Werk [10752](https://checkmk.com/werk/10752) and version 2.0.0. Since this plugin is already deprecated and it was not configurable via the *agent bakery* we assumed that this plugin is not frequently used. Therefore we decided to not fix the issue but to push the removal. We found this vulnerability internally. __Affected versions__: * 2.3.0 * 2.2.0 * 2.1.0 * 2.0.0 __Mitigations__: Migrate to the `ibm_mq` plugin. __Vulnerability Management__: We have rated the issue with a CVSS Score of 6.5 (Medium) with the following CVSS vector: `CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N`. We assigned CVE-2024-3367 to this vulnerability. __Changes__: The plugin was removed.
