In Splunk Enterprise 10.4 versions below 10.4.2, an unauthenticated user could cause Splunk Enterprise to reload token-signing keys through the Representational State Transfer (REST) API. The vulnerability does not affect Splunk Enterprise versions below 10.4. The vulnerability is possible because the REST API does not require authentication or the change_authentication capability for the token-key reload action. For more information see Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
