Summary
Splunk Enterprise from 10.4 before 10.4.3, from 10.2 before 10.2.8, from 10.0 before 10.0.11, and from 9.4 before 9.4.16 is affected. Splunk Web evaluates user-controlled expressions in Manager XML without sufficiently restricting their syntax (CWE-94). A user with the edit_manager_xml capability can run operating-system commands as the account running Splunk Enterprise by opening the affected configuration in Splunk Web Manager.

Description from the CNA
In Splunk Enterprise versions below 10.4.3, 10.2.8, 10.0.11, and 9.4.16, a user that holds a role with the edit_manager_xml capability could execute arbitrary operating-system commands using the permissions of the user account running Splunk Enterprise by opening the affected configuration in the Splunk Web Manager page. The vulnerability is possible because Splunk Web evaluates user-controlled expressions from Manager XML without sufficiently restricting the expression syntax.
