Description
In Splunk Enterprise versions below 10.2.0, 10.0.3, 9.4.9, and 9.3.9, and Splunk Cloud Platform versions below 10.2.2510.4, 10.1.2507.15, 10.0.2503.11, and 9.3.2411.123, a low-privileged user who does not hold the "admin" or "power" Splunk roles could craft a malicious payload when creating a View (Settings - User Interface - Views) at the `/manager/launcher/data/ui/views/_new` endpoint leading to a Stored Cross-Site Scripting (XSS) through a path traversal vulnerability. This could result in execution of unauthorized JavaScript code in the browser of a user. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.
