Synopsis

An application running on a remote web server host is affected by a vulnerability

Description

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2025-1006 advisory.

 - In Splunk Enterprise versions below 10.0.1, 9.4.4, 9.3.6 and 9.2.8, and Splunk Cloud Platform versions below 9.3.2411.109, 9.3.2408.119 and 9.2.2406.122, an unauthenticated attacker could trigger a blind server-side request forgery (SSRF) potentially letting an attacker perform REST API calls on behalf of an authenticated high-privileged user. (CVE-2025-20371)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Splunk Enterprise to versions 10.0.1, 9.4.4, 9.3.6, 9.2.8, or higher.Splunk is actively monitoring and patching Splunk Cloud Platform instances.
