Description
The vulnerability allows a remote attacker to perform CSRF attack.

The vulnerability exists due to incorrect validation of the HTTP request origin in Customer Groups functionality when an HTTP POST request is changed to HTTP GET on saving changes to existing groups (/customer/group/save/). The web application ignores "form_key" parameter in HTTP GET request, which allows a remote attacker to create arbitrary customer groups.
