名前: Unauthorized Error Injection Can Degrade Hardware Redundancy

An unauthorized agent can inject errors into a redundant block to deprive the system of redundancy or put the system in a degraded operating mode.

一般情報

導入モード

Architecture and Design : To ensure the performance and functional reliability of certain components, hardware designers can implement hardware blocks for redundancy in the case that others fail.
Implementation : Such issues could be introduced during implementation and identified later during Testing or System Configuration phases.
Integration : Such issues could be introduced during integration and identified later during Testing or System Configuration phases.

スコープ	影響	可能性
Integrity Availability	DoS: Crash, Exit, or Restart, DoS: Instability, Quality Degradation, DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Resource Consumption (Other), Reduce Performance, Reduce Reliability, Unexpected State 注記：This redundant block can be prevented from performing as intended if the design allows unauthorized agents to inject errors into it. In this way, a path with injected errors may become unavailable to serve as a redundant channel. This may put the system into a degraded mode of operation which could be exploited by a subsequent attack.

潜在的な緩和策

Phases : Architecture and Design
Ensure the design does not allow error injection in modes intended for normal run-time operation. Provide access controls on interfaces for injecting errors.
Phases : Implementation
Disallow error injection in modes which are expected to be used for normal run-time operation. Provide access controls on interfaces for injecting errors.
Phases : Integration
Add an access control layer atop any unprotected interfaces for injecting errors.

脆弱性マッピングノート

理由 : 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.
コメント : 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 ID	攻撃パターン名
CAPEC-624	Hardware Fault Injection The adversary uses disruptive signals or events, or alters the physical environment a device operates in, to cause faulty behavior in electronic devices. This can include electromagnetic pulses, laser pulses, clock glitches, ambient temperature extremes, and more. When performed in a controlled manner on devices performing cryptographic operations, this faulty behavior can be exploited to derive secret key information.
CAPEC-625	Mobile Device Fault Injection Fault injection attacks against mobile devices use disruptive signals or events (e.g. electromagnetic pulses, laser pulses, clock glitches, etc.) to cause faulty behavior. When performed in a controlled manner on devices performing cryptographic operations, this faulty behavior can be exploited to derive secret key information. Although this attack usually requires physical control of the mobile device, it is non-destructive, and the device can be used after the attack without any indication that secret keys were compromised.
