Splunk
Parameter Value
CVSS 5.4 (MEDIUM)
Affected Versions 10.0.0 — 9.4.14
Fixed In 9.4.14
Type CWE-79 (Cross-Site Scripting (XSS))
Vendor Splunk
Public PoC No

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.
