Date Published: 2022-11-11

QID 730643: Grafana Privilege Escalation Vulnerability

Grafana is an open-source, general purpose dashboard and graph composer, which runs as a web application.

A race condition exists in the Grafana codebase, which allows an unauthenticated user to query an arbitrary endpoint in Grafana. A race condition in the HTTP context creation could result in an HTTP request being assigned the authentication/authorization middlewares of another call. Under heavy load, it is possible that a call protected by a privileged middleware receives the middleware of a public query instead.

Affected Versions:
Grafana 9.2.x versions prior to 9.2.4.

QID Detection Logic (Unauthenticated):
This QID checks for vulnerable version of Grafana from the server response

Successful exploitation of the vulnerability may allow remote unauthenticated attacker to query protected endpoints.

CVSS V3 rated as Critical - 8.1 severity.

CVSS V2 rated as Critical - 10 severity.
