Nombre: 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.

Consecuencias comunes

Alcance Impacto Probabilidad
Availability
Access Control		Unexpected State, DoS: Crash, Exit, or Restart, DoS: Instability, Gain Privileges or Assume Identity

Note: 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.

Mitigaciones potenciales

Phases : Architecture and Design // Implementation
Define all possible states and handle all unused states through default statements. Ensure that system defaults to a secure state.

Notas de mapeo de vulnerabilidades

Justificación : 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.
Comentario : 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.
