AI risk analysis
- Summary
- This vulnerability allows unauthenticated users to execute arbitrary commands on the affected Splunk Enterprise server via the Patroni REST API, posing a significant risk to system security.
- Exploitability
- Exploitation is relatively straightforward for an attacker with network access to the REST API, as no authentication is required for critical configuration operations.
- Blast radius
- If exploited, this vulnerability could lead to complete compromise of the affected Splunk Enterprise server, potentially allowing attackers to control the system and access sensitive data.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to Splunk Enterprise version 10.4.3 or later, or apply the relevant patch for versions 10.2.7 and earlier.

NVD 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.
