Technical details

The OrderController in CoreShop through 1.5.5 fails to validate that authenticated users own the orders they are operating on, allowing arbitrary order IDs to be supplied in requests. An attacker can omit required fields in OrderConfirm or supply arbitrary shipment IDs to SendReship to confirm or modify orders belonging to other customers, compromising order integrity and customer data.
