Description

An unauthorized agent can inject errors into a redundant block to deprive the system of redundancy or put the system in a degraded operating mode.

Extended Description

To ensure the performance and functional reliability of certain components, hardware designers can implement hardware blocks for redundancy in the case that others fail. This redundant block can be prevented from performing as intended if the design allows unauthorized agents to inject errors into it. In this way, a path with injected errors may become unavailable to serve as a redundant channel. This may put the system into a degraded mode of operation which could be exploited by a subsequent attack.

This table shows the weaknesses and high level categories that are related to this weakness. These relationships are defined to give an overview of the different insight to similar items that may exist at higher and lower levels of abstraction.
