Hardware Allows Activation of Test or Debug Logic at Runtime
- Description
During runtime, the hardware allows for test or debug logic (feature) to be activated, which allows for changing the state of the hardware. This feature can alter the intended behavior of the system and allow for alteration and leakage of sensitive data by an adversary.
An adversary can take advantage of test or debug logic that is made accessible through the hardware during normal operation to modify the intended behavior of the system. For example, an accessible Test/debug mode may allow read/write access to any system data. Using error injection (a common test/debug feature) during a transmit/receive operation on a bus, data may be modified to produce an unintended message. Similarly, confidentiality could be compromised by such features allowing access to secrets.
- Common Consequences
