| スコープ | 影響 | 可能性 |
|---|---|---|
| Access Control Authorization | Bypass Protection Mechanism, Gain Privileges or Assume Identity 注記：If the logic used to determine system-security state (by leveraging the values sensed from the fuses) uses negative logic, an attacker might blow the fuse and drive the system to an insecure state. | |
| Availability | DoS: Crash, Exit, or Restart | |
| Confidentiality | Read Memory | |
| Integrity | Modify Memory, Execute Unauthorized Code or Commands |
潜在的な緩和策
Phases : Architecture and DesignLogic should be designed in a way that blown fuses do not put the product into an insecure state that can be leveraged by an attacker.
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.
