Vulnerability Title
Stored Cross-Site Scripting (XSS) through Dashboard Studio Workflow Actions in Splunk Enterprise
Source: CVE Program / CVE List V5
Vulnerability Description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the "power" Splunk role could store a Dashboard Studio workflow action with a crafted Uniform Resource Locator (URL). When another authenticated user selects the stored action from Event Actions and selects Continue, attacker-controlled JavaScript runs in the browser of that user. This could expose data or actions available through Splunk Web to that user. The vulnerability is possible because Dashboard Studio does not sufficiently validate workflow-action URLs before processing them. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the "power" Splunk role should not be able to exploit the vulnerability at will. For more information see Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
