[2.3.0] Checkmk Werk 16615 created: Remove websphere_mq plugin

[//]: # (werk v2) # Remove websphere_mq plugin key | value ---------- | --- date | 2024-03-11T11:09:48+00:00 version | 2.3.0b5 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 The plugin was already superseded by the agent plugin `ibm_mq` and deprecated with Werk [10752](https://checkmk.com/werk/10752) and version 2.0.0.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.
