Splunk · Splunk Enterprise
The Patroni REST API on search head cluster members in Splunk Enterprise (versions below 10.4.3 and 10.2.7) lacks authentication for critical configuration operations, allowing a flaw in that interface to be abused. An unauthenticated attacker with network access to that API on a search head cluster member could execute arbitrary operating-system commands, with no user interaction or authentication needed.
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.
