Summary

Splunk Enterprise versions from 10.4 before 10.4.4, from 10.2 before 10.2.8, from 10.0 before 10.0.11, and from 9.4 before 9.4.16 are affected. The federated provider REST API accepts GET requests for actions that change provider state, which enables cross-site request forgery (CWE-352). An unauthenticated attacker who tricks a user holding the edit_federated_providers capability into making a browser request can turn off all federated search providers, which temporarily stops federated searches from retrieving data from remote datasets.

Description from the CNA

In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, an unauthenticated user could trick a user that holds a role with the edit_federated_providers capability into turning off all federated search providers. Successful exploitation could temporarily prevent federated searches from retrieving data from remote datasets. The vulnerability is possible because the federated provider Representational State Transfer (REST) API accepts GET requests for actions that change provider state. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will. For more information see Run federated searches over remote Splunk platform deployments (https://help.splunk.com/en/splunk-enterprise/search/federated-search/10.6/run-federated-searches-across-other-splunk-deployments/run-federated-searches-over-remote-splunk-platform-deployments) and 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.
