Advisory ID: SVD-2023-0801

CVE ID: CVE-2023-40592

Published: 2023-08-30

Last Update: 2023-10-18

CVSSv3.1 Score: 8.4, High


Bug ID: VULN-5287


In Splunk Enterprise versions below 9.1.1, 9.0.6, and 8.2.12, an attacker can craft a special web request that can result in reflected cross-site scripting (XSS) on the “/app/search/table” web endpoint, which presents as the “Create Table View” page in Splunk Web. Exploitation of this vulnerability can lead to the execution of arbitrary commands on the Splunk platform instance.

A JavaScript file within this web endpoint does not properly validate input which lets an attacker insert a payload into a function.


Upgrade Splunk Enterprise to versions 8.2.12, 9.0.6, or 9.1.1.

Splunk is actively monitoring and patching Splunk Cloud Platform instances.
