Pimcore Ecommerce Framework Bundle Improper Access Control allows unprivileged user to access back-office orders list

Summary

An authenticated and unauthorized user can access the back-office orders list and be able to query over the information returned.

Details

Permissions do not seem to be enforced when reaching the admin/ecommerceframework/admin-order/list endpoint allowing an authenticated user without the permissions to access the endpoint and query the data available there. It seems that the access control is not enforced in this place :

https://github.com/pimcore/ecommerce-framework-bundle/blob/ff6ff287b6eb468bb940909c56970363596e5c21/src/Controller/AdminOrderController.php#L98

Note : Testing this vulnerability requires a fully configured ecommerce website, but it looks vulnerable as when requesting the endpoint the data seem returned (and when looking at the source code nothing seems to validate the permissions on the specified endpoint).

PoC

In order to reproduce the issue, the following steps can be followed :

1. As an administrator : a. Create a role without any permission through Settings → User & Roles → Roles in the administration panel b. Create an user through Settings → User & Roles → Users and assign it the unprivileged role previously created
2. Log out the current administrator and log in with this new user
3. Access to the following endpoint https://pimcore_instance/admin/ecommerceframework/admin-order/list and the results will be returned to this unauthorized user

Impact

An unauthorized user can access back-office orders without being authorized to.
