What to Know
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could perform Remote Code Execution (RCE) by submitting crafted Splunk Web Manager Configuration content. The user could then access all relevant data and affect system integrity and availability. The vulnerability is possible because Splunk Web evaluates manager Extensible Markup Language expressions without sufficient input restrictions, and the associated configuration route does not require the capability expected for manager configuration changes. For more information see About configuration files (https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.4/administer-splunk-enterprise-with-configuration-files/about-configuration-files) in the Splunk documentation.
