Official description

Grafana is an open-source platform for monitoring and observability. The vulnerability impacts Grafana instances with several organizations, and allows a user with Organization Admin permissions in one organization to change the permissions associated with Organization Viewer, Organization Editor and Organization Admin roles in all organizations. It also allows an Organization Admin to assign or revoke any permissions that they have to any user globally. This means that any Organization Admin can elevate their own permissions in any organization that they are already a member of, or elevate or restrict the permissions of any other user. The vulnerability does not allow a user to become a member of an organization that they are not already a member of, or to add any other users to an organization that the current user is not a member of.

The underlying weakness: Improper Privilege Management

The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
