Nome: Security Version Number Mutable to Older Versions

The security version number in the hardware product is mutable, resulting in the ability to downgrade (roll-back) the boot firmware to vulnerable code versions.

Consequências Comuns

Escopo	Impacto	Probabilidade
Confidentiality Integrity Authentication Authorization	Other, Alter Execution Logic, Unexpected State Nota: If the security version number is modifiable by an adversary, this allows attacks like downgrading to a previous version that contains vulnerabilities. Once downgraded to a previous version, an adversary can launch exploits on the SoC and thus compromise the security of the SoC. These downgrade attacks are also referred to as roll-back attacks.	High
Availability	Other, Alter Execution Logic, Unexpected State Nota: An adversary could prevent upgrades, casing a denial of service.

Mitigações Potenciais

Phases : Architecture and Design
The security version number must be stored securely and persistently across power-on resets. When architecting the system, security version data should be designated for storage in registers that are either read-only or have access controls that prevent modification by an untrusted agent.
Phases : Implementation
During implementation and test, security version data should be demonstrated to be read-only and access controls should be validated.

Métodos de Detecção

Automated Dynamic Analysis

Mutability of stored security version numbers and programming with older firmware images should be part of automated testing.
Eficácia : High

Architecture or Design Review

Anti-roll-back features should be reviewed as part of Architecture or Design review.

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-176	Configuration/Environment Manipulation An attacker manipulates files or settings external to a target application which affect the behavior of that application. For example, many applications use external configuration files and libraries - modification of these entities or otherwise affecting the application's ability to use them would constitute a configuration/environment manipulation attack.
