Description
CoreShop through 1.5.5 contains an authorization bypass vulnerability in the OrderController that allows authenticated customers to act on other customers' orders by supplying user-controlled ids. Attackers can omit the data field in OrderConfirm or supply another reshipId to SendReship to confirm receipt of others' orders and overwrite return tracking details.
