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-2025-0305 advisory.

 - In Splunk Enterprise versions below 9.4.1, 9.3.3, 9.2.5, and 9.1.8 and Splunk Cloud Platform versions below 9.3.2408.107, 9.2.2406.111, and 9.1.2308.214, a low-privileged user that does not hold the admin or power Splunk roles could run a saved search with a risky command using the permissions of a higher- privileged user to bypass the SPL safeguards for risky commands on the /services/streams/search endpoint through its q parameter. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will. (CVE-2025-20226)

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 9.4.1, 9.3.3, 9.2.5, 9.1.8, or higher.Splunk is actively monitoring and patching Splunk Cloud Platform instances.
