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 execute arbitrary code on the Splunk platform instance through Splunk Web Manager Configuration. The user could then access all relevant data and affect system integrity and availability on the Splunk platform instance. The vulnerability is possible because Splunk Web Manager Configuration evaluates manager configuration values, and the Representational State Transfer (REST) API path for manager configuration does not require the permission that normally controls manager configuration writes. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access) and restmap.conf (https://help.splunk.com/en/data-management/splunk-enterprise-admin-manual/10.2/configuration-file-reference/10.2.0-configuration-file-reference/restmap.conf) in the Splunk documentation.
