Official CWE Definition
CWE-1313: Hardware Allows Activation of Test or Debug Logic at Runtime
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.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- Missing validation
- Unsafe defaults
- Insufficient authorization or memory-safety invariant
Remediation
- Architecture and Design: Insert restrictions on when the hardware's test or debug features can be activated. For example, during normal operating modes, the hardware's privileged modes that allow access to such features cannot be activated. Configuring the hardware to only enter a test or debug mode within a window of opportunity such as during boot or configuration stage. The result is disablement of such test/debug features and associated modes during normal runtime operations.
- Implementation: Insert restrictions on when the hardware's test or debug features can be activated. For example, during normal operating modes, the hardware's privileged modes that allow access to such features cannot be activated. Configuring the hardware to only enter a test or debug mode within a window of opportunity such as during boot or configuration stage. The result is disablement of such test/debug features and associated modes during normal runtime operations.
- Integration: Insert restrictions on when the hardware's test or debug features can be activated. For example, during normal operating modes, the hardware's privileged modes that allow access to such features cannot be activated. Configuring the hardware to only enter a test or debug mode within a window of opportunity such as during boot or configuration stage. The result is disablement of such test/debug features and associated modes during normal runtime operations.
