名稱: Improper Finite State Machines (FSMs) in Hardware Logic
Faulty finite state machines (FSMs) in the hardware logic allow an attacker to put the system in an undefined state, to cause a denial of service (DoS) or gain privileges on the victim's system.

| 範圍 | 影響 | 可能性 |
|---|---|---|
| Availability Access Control | Unexpected State, DoS: Crash, Exit, or Restart, DoS: Instability, Gain Privileges or Assume Identity 注意：Faulty FSM designs that do not account for all states, either through undefined states (left as don't cares) or through incorrect implementation, might lead an attacker to drive the system into an unstable state from which the system cannot recover without a reset, thus causing a DoS. Depending on what the FSM is used for, an attacker might also gain additional privileges to launch further attacks and compromise the security guarantees. |
潛在緩解措施
Phases : Architecture and Design // ImplementationDefine all possible states and handle all unused states through default statements. Ensure that system defaults to a secure state.
漏洞對應備注
理由說明 : 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.備註 : 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.
