How to fix?

Upgrade github.com/rancher/rancher/app to version 2.0.14, 2.1.9, 2.2.2 or higher.

Overview

github.com/rancher/rancher/app is a complete container management platform

Affected versions of this package are vulnerable to Improper Authentication. When Rancher starts for the first time, it creates a default admin user with a well-known password. After initial setup, the Rancher administrator may choose to delete this default admin user. If Rancher is restarted, the default admin user will be recreated with the well-known default password. An attacker could exploit this by logging in with the default admin credentials.

Note:

This can be mitigated by deactivating the default admin user rather than completely deleting them.
