Vulnerability 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 perform Remote Code Execution (RCE) by uploading a malicious knowledge bundle and causing it to be used by distributed search, which can allow for access to all relevant data and affect system integrity and availability. The vulnerability is possible because the Representational State Transfer (REST) API endpoint for knowledge bundle upload does not require the high-privilege capability edit_dist_peer, and distributed search accepts caller-supplied knowledge bundle selections from users who do not hold that capability.
