Checkmk Werk 14077: NagVis Geomaps: Deprecate <tt>wato_geo_fields.py</tt> in favor of regular custom host attributes

by Joerg Herbel

ID: 14077 Title: NagVis Geomaps: Deprecate <tt>wato_geo_fields.py</tt> in favor of regular custom host attributes Component: Setup Level: 1 Class: Bug fix Version: 2.2.0i1 This werk only affects users of NagVis Geomaps. One of the available map types in NagVis are Geomaps, which show geographical locations. For this map type, NagVis offers the option to use geographical coordinates stored in Checkmk host attributes, see http://docs.nagvis.org/1.9/en_US/geomap.html. The necessary host attributes (latitude and longitude) are by default not available in Checkmk. Therefore, up to now, Checkmk came with the script <tt>share/doc/check_mk/treasures/wato_geo_fields.py</tt>, which added these host attributes. As of this werk, <tt>wato_geo_fields.py</tt> is deprecated, since it is incompatible with Checkmk 2.1. Attempting to use this script in version 2.1 will fail, meaning that latitude and longitude will no longer available in the user interface. Furthermore, the REST API will respond with HTTP 500 when attempting to query the status of affected hosts. To retain the functionality previously offered by this script, users can instead create two regular custom host attributes. This is fully compatible and will not result in any loss of data. The exact procedure is described here: https://kb.checkmk.com/display/KB/Geo+coordinates+from+Checkmk+in+NagVis+ma…. After creating the custom attributes, users must remove their local copy of <tt>wato_geo_fields.py</tt> from <tt>local/share/check_mk/web/plugins/wato/<tt>.

Checkmk Werk 13420: Fix section parsing with different separators

by Benedikt Seidl

ID: 13420 Title: Fix section parsing with different separators Component: Core & setup Level: 1 Class: Bug fix Version: 2.2.0i1 In checkmk it's possible to transport a single section with different separators: <code> <<<section:sep(44)>>> a,1 <<<section:sep(124)>>> b|2 <<<section:sep(44)>>> c,3 </code> Up until this werk, the ordering of the lines where not preserved, the check function would have received them as a,1 c,3 b,2

Checkmk Werk 13724: Remove legacy macro expansion in Event Console script actions

by Maximilian Wirtz

ID: 13724 Title: Remove legacy macro expansion in Event Console script actions Component: Event Console Level: 2 Class: Security fix Version: 2.2.0i1 The Event Console is able to execute actions, e.g. shell scripts, when opening or cancelling events. Details of the events are available to the script via environment variables <tt>CMK_</tt> as described in the user manual (https://docs.checkmk.com/latest/en/ec.html#_shell_scripts_and_emails). This mechanism will keep working as before. However, there is a second undocumented mechanism which relies on macro expansion in the shell scripts. Previously it was possible to use macros (e.g. <tt>$HOST$</tt>) in the <i>Event Console</i> scripts. These were replaced before executing the script. The values of these macros can be untrusted input and lead to command injections. You are only affected by this issue, if your scripts use the macro expansion. With this incompatible change we remove the macro expansion mechanism for security reasons. The site update mechanism tries to detect Event Console actions using these macros, disables the actions and informs you about this change. The output of an <tt>omd update</tt> for a rule being disabled would look like this: C+: "Script 'some_action_id' uses macros. We disable it. Please replace the macros with proper variables before enabling it again!" C-: If you use the <i>Event Console</i> with shell script actions you should check your scripts for macros and replace them with the documented environment variable approach (Setup > Events > Event Console rule packs > Event Console configuration > Event Console configuration). You can access all macro values with environment variables (they are prefixed with <tt>CMK_</tt>).
