Nome: Hardware Child Block Incorrectly Connected to Parent System

Signals between a hardware IP and the parent system design are incorrectly connected.

General Informations

Background Details

Modes Of Introduction

Implementation : This weakness is introduced when integrating IP into a parent design.

Conseguenze comuni

Confidentiality
Integrity
Availability		Varies by Context

Nota: This may cause security risks. For example, if the IP should only be reset by a system-wide hard reset, but instead the reset input is connected to a software-triggered debug mode reset (which is also asserted during a hard reset), integrity of data inside the IP can be violated.

Potential Mitigations

Phases : Testing
System-level verification may be used to ensure that components are correctly connected and that design security requirements are not violated due to interactions between various IP blocks.

Note sulla mappatura delle vulnerabilità

Giustificazione : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Commento : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
