CVE-2022-21703 vulnerability in Grafana Labs and Other Products
Published on February 8, 2022

Cross Site Request Forgery in Grafana

Grafana is an open-source platform for monitoring and observability. Affected versions are subject to a cross site request forgery vulnerability which allows attackers to elevate their privileges by mounting cross-origin attacks against authenticated high-privilege Grafana users (for example, Editors or Admins). 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. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.

What is a Session Riding Vulnerability?

The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. When a web server is designed to receive a request from a client without any mechanism for verifying that it was intentionally sent, then it might be possible for an attacker to trick a client into making an unintentional request to the web server which will be treated as an authentic request. This can be done via a URL, image load, XMLHttpRequest, etc. and can result in exposure of data or unintended code execution.

CVE-2022-21703 has been classified to as a Session Riding vulnerability or weakness.
