Summary
In Splunk Enterprise versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and versions below 3.9.10, 3.8.58 and 3.7.28 of the Splunk Secure Gateway app on Splunk Cloud Platform, a low-privileged user that does not hold the "admin" or "power" Splunk roles could craft a malicious payload through the `label` column field after adding a new device in the Splunk Secure Gateway app. This could potentially lead to a client-side denial of service (DoS).
