Summary
Grafana Cross Site Request Forgery (CSRF)
Details

Today we are releasing Grafana 8.3.5 and 7.5.15. This patch release includes MEDIUM severity security fix for Cross Site Request Forgery for Grafana.

Release v.8.3.5, only containing security fixes:

Release v.7.5.15, only containing security fixes:

CSRF (CVE-2022-21703)

Summary

On Jan. 18, security researchers jub0bs and abrahack contacted Grafana to disclose a CSRF vulnerability which allows anonymous attackers to elevate their privileges by mounting cross-origin attacks against authenticated high-privilege Grafana users (for example, Editors or Admins).

We believe that this vulnerability is rated at CVSS 6.8 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:N/A:N).

Impact

An attacker can exploit this vulnerability for privilege escalation by tricking an authenticated user into inviting the attacker as a new user with high privileges.

Affected versions with MEDIUM severity

All Grafana >=3.0-beta1 versions are affected by this vulnerability.

Solutions and mitigations

All installations after Grafana v3.0-beta1 should be upgraded as soon as possible.

Note that if you are running Grafana behind any reverse proxy, you need to make sure that you are passing the original Host and Origin headers from the client request to Grafana.

In the case of Apache Server, you need to add ProxyPreserveHost on in your proxy configuration. In case of NGINX, you can need to add proxy_set_header Host $http_host; in your configuration.

Appropriate patches have been applied to Grafana Cloud and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana.
