## Overview

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.

## Affected

- `enterprise >= 10.4 < 10.4.4`
- `enterprise >= 10.2 < 10.2.8`
- `enterprise >= 10.0 < 10.0.11`
- `enterprise >= 9.4 < 9.4.16`
- `secure_gateway >= 3.10 < 3.10.12`
- `secure_gateway >= 3.9 < 3.9.26`
- `secure_gateway >= 3.8 < 3.8.73`

## Remediation

Upgrade Splunk Enterprise to versions 10.4.4, 10.2.8, 10.0.11, and 9.4.16 or higher.

Upgrade Splunk Secure Gateway to versions 3.10.12, 3.9.26, and 3.8.73 or higher.

### Workarounds

Turn off or remove the Splunk Secure Gateway app. See [Manage app and add-on objects](https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.2/meet-splunk-apps/manage-app-and-add-on-objects) in the Splunk documentation.
Note: Splunk Mobile, Spacebridge, and Mission Control rely on functionality in the Splunk Secure Gateway app. If you do not use any of these apps, features, or functionality, as a potential mitigation, you may turn off or remove the app.
