CyberRota Analysis

AI-Generated

Splunk Enterprise versions prior to 10.4.2, 10.2.6, 10.0.9, and 9.4.14 are vulnerable due to insufficient validation of workflow-action URLs in Dashboard Studio, allowing users with the "power" role to store malicious URLs that execute attacker-controlled JavaScript in the browsers of other authenticated users. This could lead to unauthorized data exposure or actions within Splunk Web. Organizations using affected versions, particularly those with users assigned the "power" role, should prioritize patching to mitigate the risk of exploitation through phishing attacks.

Original NVD 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.
