Description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could inject Search Processing Language (SPL) into saved-search dispatch requests. This could allow for unauthorized access to all relevant data and affect system integrity within Splunk Enterprise. The vulnerability is possible because Splunk Enterprise does not correctly validate caller-supplied time values before using them in saved-search dispatch. For more information see Search endpoint descriptions (https://help.splunk.com/en/splunk-enterprise/rest-api-reference/10.2/search-endpoints/search-endpoint-descriptions) in the Splunk documentation.
