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-2025-0708 advisory.

 - In Splunk Enterprise versions below 9.4.2, 9.3.5, 9.2.6, and 9.1.9 and Splunk Cloud Platform versions below 9.3.2411.103, 9.3.2408.112, and 9.2.2406.119, a low-privileged user that does not hold the admin or power Splunk roles, and has read-only access to a specific alert, could suppress that alert when it triggers. See Define alert suppression groups to throttle sets of similar alerts. (CVE-2025-20300)

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 9.4.2, 9.3.5, 9.2.6, 9.1.9, or higher.Splunk is actively monitoring and patching Splunk Cloud Platform instances.
