Description
In Splunk Enterprise versions below 10.4.1, 10.2.6, 10.0.8, and 9.4.13, a user who does not hold the "admin" or "power" Splunk roles could trick another user into running arbitrary Search Processing Language (SPL) commands through the Data Model Editor using the permissions of the affected user. The commands could access all relevant data available to the affected user and affect system integrity. The vulnerability is possible because Splunk Web does not apply SPL safeguards for risky commands when the Data Model Editor runs the base search for auto-extracted fields. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who does not hold the "admin" or "power" Splunk roles should not be able to exploit the vulnerability at will. For more information see SPL safeguards for risky commands (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/best-practices-for-splunk-platform-security/spl-safeguards-for-risky-commands) and Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
