Denial of Service (DoS) through “User Interface - Views“ configuration page in Splunk Enterprise

Advisory ID: SVD-2025-0703

CVE ID: CVE-2025-20320

Published: 2025-07-07

Last Update: 2025-07-07

CVSSv3.1 Score: 6.3, Medium

CWE: CWE-35

Bug ID: VULN-31600

Description

In Splunk Enterprise versions below 9.4.3, 9.3.5, 9.2.7 and 9.1.10, and Splunk Cloud Platform versions below 9.3.2411.107, 9.3.2408.117, and 9.2.2406.121, a low-privileged user that does not hold the “admin“ or “power“ Splunk roles could craft a malicious payload through the User Interface - Views configuration page that could potentially lead to a denial of service (DoS).
The user could cause the DoS by exploiting a path traversal vulnerability that allows for deletion of arbitrary files within a Splunk directory.

The vulnerability requires the low-privileged user to phish the administrator-level victim by tricking them into initiating a request within their browser. The low-privileged user should not be able to exploit the vulnerability at will.

Solution

Upgrade Splunk Enterprise to versions 9.4.3, 9.3.5, 9.2.7, 9.1.10, or higher.

Splunk is actively monitoring and patching Splunk Cloud Platform instances.
