Low risk15th percentile - higher than 15% of all known CVEs
Summary
A user without the "admin" or "power" roles can store a dashboard view that runs JavaScript in another user's browser when they open it and hover over a sparkline table cell, potentially allowing access to all relevant data and system integrity. The vulnerability is due to insufficient restriction of tooltip options and lack of escaping tooltip content before display.
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 does not hold the "admin" or "power" Splunk roles could store a dashboard view that runs JavaScript in the browser of another user who opens it and hovers over a sparkline table cell, allowing for access to all relevant data and system integrity available to that user. The vulnerability is possible because the dashboard table renderer does not sufficiently restrict tooltip options or escape tooltip content before display.
