CVE-2023-0594: XSS
Grafana is an open-source platform for monitoring and observability.
Starting with the 7.0 branch, Grafana had a stored XSS vulnerability in the trace view visualization.
The stored XSS vulnerability was possible due the value of a span's attributes/resources were not properly sanitized and this will be rendered when the span's attributes/resources are expanded.
An attacker needs to have the Editor role in order to change the value of a trace view visualization to contain 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.
Users may upgrade to version 8.5.21, 9.2.13 and 9.3.8 to receive a fix.
Other sources
We discovered that when showing data in a trace view visualization, some parts of it are not sanitized. One can provide HTML including JavaScript as the value of a span’s attributes/resources and this will be rendered when the span’s attributes/resources are expanded. A malicious user with the ability to introduce trace data could provide a JavaScript that changes the password for the user viewing the trace view (this could be an admin) to a known password, thus getting access to the admin account.
