In Splunk Enterprise versions below 8.1.13, 8.2.10, and 9.0.4, the ‘search_listener’ parameter in a search allows for a blind server-side request forgery (SSRF) by an authenticated user. The initiator of the request cannot see the response without the presence of an additional vulnerability within the environment.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
