## Description

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 inject arbitrary Search Processing Language (SPL) commands through the geostats command. The injected SPL runs with the permissions of another authenticated user after that user initiates the attacker-controlled geostats search in Splunk Web. The injected SPL could expose all relevant data available to the second user, including stored credentials, and modify lookup files that the second user has permission to change. The vulnerability is possible because the geostats command does not sufficiently validate input before Splunk Enterprise processes it. 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 geostats (https://help.splunk.com/en/splunk-enterprise/spl-search-reference/10.0/search-commands/geostats) in the Splunk documentation.
