Pimcore Customer Data Framework Improper Access Control allows unprivileged user to access GDPR extracts
Summary
An authenticated and unauthorized user can access the GDPR data extraction feature and query over the information returned, leading to customer data exposure.
Details
Permissions do not seem to be enforced when reaching the /admin/customermanagementframework/gdpr-data/search-data-objects 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/customer-data-framework/blob/b4af625ef327c58d05ef7cdf145fa749d2d4195e/src/Controller/Admin/GDPRDataController.php#L38
PoC
In order to reproduce the issue, the following steps can be followed:
- 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
- Log out the current administrator and log in with this new user
- Access to the following endpoint
https://pimcore_instance/admin/customermanagementframework/gdpr-data/search-data-objects?id=&firstname=&lastname=&email=&page=1&start=0&limit=50and the results will be returned to this unauthorized user.
Impact
An unauthorized user can access PII data from customers without being authorized to.
