Splunk: CVE-2024-36990: Denial of Service (DoS) on the datamodel/web REST endpoint

In Splunk Enterprise versions below 9.2.2, 9.1.5, and 9.0.10 and Splunk Cloud Platform versions below 9.2.2403.100, an authenticated, low-privileged user that does not hold the “admin” or “power” Splunk roles could send a specially crafted HTTP POST request to the datamodel/web REST endpoint in Splunk Enterprise, potentially causing a denial of service.The DoS could result from a condition where a data model definition contains a cyclic dependency. That dependency could lead to an infinite loop, which leads to a stack overflow and the subsequent crash of the Splunk daemon.
