Vendor Solution
Upgrade Splunk Enterprise to versions 10.4.3, 10.2.7, 10.0.10, and 9.4.15, or higher.
Vendor Workaround
Turn off the PostgreSQL sidecar by setting `disabled = true` in the `[postgres]` stanza of `$SPLUNK_HOME/etc/system/local/server.conf` if you do not use Edge Processor, OpAmp, or SPL2 data pipelines. Restart Splunk Enterprise to apply the change. For more information see [Sidecar configuration settings](https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.2/splunk-sidecars/sidecar-configuration-settings) and [server.conf](https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.2/configuration-file-reference/10.2.7-configuration-file-reference/server.conf) in the Splunk documentation.

| Description | In Splunk Enterprise versions below 10.4.3 and 10.2.7, an unauthenticated user with network access to the Patroni Representational State Transfer (REST) Application Programming Interface (API) on a search head cluster member could execute attacker-controlled operating-system commands. The vulnerability is possible because this interface does not require authentication for critical configuration operations. For more information see Sidecar configuration settings (https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.2/splunk-sidecars/sidecar-configuration-settings) in the Splunk documentation. Splunk Enterprise versions 10.0.x and 9.4.x are not affected. | |
