Summary

Splunk Enterprise from 10.4 before 10.4.4, 10.2 before 10.2.8, 10.0 before 10.0.11 and 9.4 before 9.4.16 and Splunk Secure Gateway from 3.10 before 3.10.12, 3.9 before 3.9.26 and 3.8 before 3.8.73 are affected. Splunk Secure Gateway does not neutralize special characters in values before creating filters (CWE-943). A low-privileged user who lacks the admin and power roles can view dashboard and report listings beyond the requested filter scope, within objects that user can access.

Description from the CNA

In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, and Splunk Secure Gateway versions below 3.10.12, 3.9.26, and 3.8.73, a user who does not hold the "admin" or "power" Splunk roles could view dashboard and report listings beyond the requested filter scope while remaining within objects that the user can access. The vulnerability is possible because Splunk Secure Gateway does not neutralize special characters in values before it creates filters for dashboard and report requests. 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) in the Splunk documentation.
