| 影响范围 | 影响 | 可能性 |
|---|---|---|
| Access Control Authentication Authorization | Varies by Context 注意： 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. |
潜在缓解措施
Phases : ImplementationDesign 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.
漏洞映射说明
依据 : 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.备注 : 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.
