Summary
A user with the "power" role can create a malicious Splunk Web tour and cause arbitrary JavaScript to run in another user's browser when they open a crafted tour link. The JavaScript runs in the victim's browser, allowing access to all relevant data. The XSS vulnerability is due to insufficient output encoding of tour content and navigation links and accepting a tour selector value that can be treated as markup.
Risk Assessment
An attacker could execute arbitrary JavaScript in the victim's browser, potentially leading to data theft or system integrity compromise.
Recommendation
Upgrade Splunk Enterprise to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later to remediate the vulnerability.
Original NVD description (English source)
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 create a malicious Splunk Web tour and cause arbitrary JavaScript to run in the browser of another user when that user opens a crafted tour link. The JavaScript runs in the browser of the affected user, allowing for access to all relevant data available to that user. The Cross-Site Scripting (XSS) vulnerability is possible because Splunk Web renders tour content and tour navigation links without sufficient output encoding and accepts a tour selector value that can be treated as markup. The vulnerability requires another user to open a crafted tour link. The user who holds the "power" Splunk role should not be able to trigger JavaScript execution in another user's browser without that user interaction.
