Description
In Splunk Enterprise versions below 10.4.4, a user that holds a role with the preview_data_management_pipeline capability or edit_data_management_pipeline_job capability could read or delete Data Management SPL2 preview jobs and results outside their ownership scope.
The vulnerability is possible because the Data Management Representational State Transfer (REST) API verifies the required capability but does not verify that the requested preview job belongs to the requester.
The affected Data Management REST API is available only when the Edge Processor feature is turned on. The Edge Processor feature is turned off by default.

Remediation

Vendor Solution

Upgrade Splunk Enterprise to versions 10.4.4, 10.2.8, 10.0.11, and 9.4.16 or higher.


Vendor Workaround

Turn off the SPL2 preview sidecar by setting `spl2_preview_enabled` to `false` in the `server.conf` configuration file if you do not use SPL2 previews for Edge Processor pipelines. Restart Splunk Enterprise for the change to take effect. For more information see the [server.conf configuration specification file](https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.4/configuration-file-reference/10.4.4-configuration-file-reference/server.conf) in the Splunk documentation.
