CWE-1315—Improper Setting of Bus Controlling Capability in Fabric End-point

名称

Improper Setting of Bus Controlling Capability in Fabric End-point

描述

The bus controller enables bits in the fabric end-point to allow responder devices to control transactions on the fabric.

To support reusability, certain fabric interfaces and end points provide a configurable register bit that allows IP blocks connected to the controller to access other peripherals connected to the fabric. This allows the end point to be used with devices that function as a controller or responder. If this bit is set by default in hardware, or if firmware incorrectly sets it later, a device intended to be a responder on a fabric is now capable of controlling transactions to other devices and might compromise system security.
