medium Nessus Plugin ID 299412

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-2026-0206 advisory.

- In Splunk Enterprise versions below 10.0.2, 10.0.3, 9.4.8, and 9.3.9, a low-privileged user who does not hold the admin Splunk role could access the Splunk Monitoring Console App endpoints due to an improper access control. This could lead to a sensitive information disclosure. The Monitoring Console app is a bundled app that comes with Splunk Enterprise. It is not available for download on SplunkBase, and is not installed on Splunk Cloud Platform instances. This vulnerability does not affect Cloud Monitoring Console.
(CVE-2026-20141)

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 10.0.2, 10.0.3, 9.4.8, 9.3.9, or higher. The vulnerability does not affect Splunk Cloud Platform instances.
