Summary
In Splunk Enterprise versions below 10.4.2 and 10.2.6, a user without 'admin' or 'power' roles can delete SPL2 modules belonging to other users through the data management orchestrator interface. The vulnerability is due to missing ownership verification before deletion (broken object level authorization).
Risk Assessment
An attacker could delete critical SPL2 modules of other users, potentially disrupting applications and causing data loss or service outages.
Recommendation
Upgrade Splunk Enterprise to version 10.4.2 or 10.2.6 or later. Restrict access to the data management orchestrator interface to trusted users only.
Original NVD description (English source)
In Splunk Enterprise versions below 10.4.2 and 10.2.6, a user who does not hold the "admin" or "power" Splunk roles could delete Splunk Processing Language version 2 (SPL2) modules belonging to other users through the data management orchestrator interface. The vulnerability does not affect Splunk Enterprise versions below 10.2. The broken object level authorization is possible because the data management orchestrator does not verify that the requesting user owns the target resources before it deletes the modules. For more information see Manage SPL2-based apps (https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/meet-splunk-apps/manage-spl2-based-apps) in the Splunk documentation.
