Access Control
Authentication
Authorization		Varies by Context

Nota: When the device is first brought out of reset, the state of registers will be indeterminate if they have not been initialized by the logic. Before the registers are initialized, there will be a window during which the device is in an insecure state and may be vulnerable to attack.

Potential Mitigations

Phases : Implementation
Design checks should be performed to identify any uninitialized flip-flops used for security-critical functions.
Phases : Architecture and Design
All registers holding security-critical information should be set to a specific value on reset.

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.
