AI-Generated

Splunk Enterprise and Splunk Secure Gateway versions prior to specified updates are vulnerable to Server-Side Request Forgery (SSRF), allowing unauthorized users to send authenticated requests to internal services. This could lead to unauthorized changes in the Search Head Cluster state and potential denial of service. Organizations using affected versions, particularly those with users lacking admin or power roles, should prioritize patching to mitigate this risk.

Original NVD Description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.9, 3.9.23, and 3.8.70, a user who does not hold the "admin" or "power" Splunk roles could use Server-Side Request Forgery (SSRF) in report notifications to send system-authenticated requests to internal Splunk services, which could allow for changes to Search Head Cluster state and a denial of service. The vulnerability is possible because Splunk Secure Gateway does not validate report notification path values before it sends internal requests.
