Description
Nagios Log Server before 2024R1.3.2 allows authenticated users (with read-only API access) to stop the Elasticsearch service via a /nagioslogserver/index.php/api/system/stop?subsystem=elasticsearch call. The service stops even though "message": "Could not stop elasticsearch" is in the API response. This is GL:NLS#474.
