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

The firewall in an on-chip fabric protects the main addressed region, but it does not protect any mirrored memory or memory-mapped-IO (MMIO) regions.

Mitigações Potenciais

Phases : Architecture and Design
The 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.

Métodos de Detecção

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.
Eficácia : High

Notas de Mapeamento de Vulnerabilidade

Justificativa : 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.
Comentário : 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.

Padrões de Ataque Relacionados

CAPEC-ID Nome do Padrão de Ataque
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.
