Description
On 2022-12-16 during an internal audit of Grafana, a member of the security team found a stored XSS vulnerability affecting the core plugin GeoMap.
The stored XSS vulnerability was possible due to SVG-files weren't properly sanitized and allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana instance.
Impact
An attacker needs to have the Editor role in order to change a panel to include either an external URL to a SVG-file containing JavaScript, or use the data: scheme to load an inline SVG-file containing JavaScript. This means that vertical privilege escalation is possible, where a user with Editor role can change to a known password for a user having Admin role if the user with Admin role executes malicious JavaScript viewing a dashboard.
Impacted versions
All installations for Grafana versions >=8.1.x.
Solutions and mitigations
Update your Grafana instance.
