Summary

Splunk Enterprise 10.4 before 10.4.3, 10.2 before 10.2.7, 10.0 before 10.0.10 and 9.4 before 9.4.15 are affected, as are Splunk Secure Gateway 3.10 before 3.10.11, 3.9 before 3.9.25 and 3.8 before 3.8.72. Splunk Secure Gateway does not verify that the user is authorized to request a signature (CWE-862). A remote user with low privileges who does not hold the admin or power role can make it sign attacker-controlled payloads.

Description from the CNA

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15, a user who does not hold the "admin" or "power" Splunk roles could cause Splunk Secure Gateway to sign attacker-controlled payloads. The vulnerability is possible because Splunk Secure Gateway does not verify that the user is authorized to request a signature. Splunk Secure Gateway versions below 3.10.11, 3.9.25, and 3.8.72 are also affected. For more information see Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
