Splunk Enterprise 9.2 < 9.2.10, 9.3 < 9.3.8, 9.4 < 9.4.6, 10.0 < 10.0.2 (SVD-2025-1208)

medium Nessus Plugin ID 277113

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-2025-1208 advisory.

- In Splunk Enterprise versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and versions below 3.9.10, 3.8.58 and 3.7.28 of the Splunk Secure Gateway app on Splunk Cloud Platform, a low-privileged user that does not hold the admin or power Splunk roles could craft a malicious payload through the `label` column field after adding a new device in the Splunk Secure Gateway app. This could potentially lead to a client-side denial of service (DoS). (CVE-2025-20389)

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, 9.4.6, 9.3.8, 9.2.10, or higher.Splunk is actively monitoring and patching Splunk Cloud Platform instances.
