Description
IoTSharp through 3.6.1 contains an insecure direct object reference vulnerability that allows any authenticated user to read other tenants' data because Customers and Devices API handlers do not scope queries to the caller's tenant. Attackers can self-register through the anonymous AccountController.Create endpoint and supply other tenants' GUIDs to read customer contact details, device inventories and device attribute telemetry.
