名称: Missing Protection for Mirrored Regions in On-Chip Fabric Firewall

潜在缓解措施
Phases : Architecture and DesignThe fabric firewall should apply the same protections as the original region to the mirrored regions.
Phases : Implementation
The fabric firewall should apply the same protections as the original region to the mirrored regions.
检测方法
Manual Dynamic Analysis
Using an external debugger, send write transactions to mirrored regions to test if original, write-protected regions are modified. Similarly, send read transactions to mirrored regions to test if the original, read-protected signals can be read.有效性 : High
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.

|---|---|
| CAPEC-456 | Infected Memory
An adversary inserts malicious logic into memory enabling them to achieve a negative impact. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems that are still under development and part of the supply chain. |
