Improper authentication - CVE-2022-39229

Summary

On September 7 as a result of an internal security audit we have discovered a security vulnerability in Grafana basic authentication, related to the usage of username and email address.

In Grafana, a user’s username and email address are unique fields, that means no other user can have the same username or email address as another user.

In addition, a user can have an email address as a username and Grafana login allows users to sign in with either username or email address. This creates an unusual behavior, where user1_ can register with one email address and user2_ can register their username as user1’s email address. As a result, _user1_ would be prevented to sign in Grafana, since user1_ password won’t match with users2_ email address.

The CVSS score for this vulnerability is 4.3 Moderate (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L).

Impacted versions

All installations for Grafana versions <=9.x, <=8.x
