Improper Finite State Machines (FSMs) in Hardware Logic
CWE-1245
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.
The functionality and security of the system heavily depend on the implementation of FSMs. FSMs can be used to indicate the current security state of the system. Lots of secure data operations and data transfers rely on the state reported by the FSM.
We track 1 vulnerability of this type. 100% are rated high or critical, and the average CVSS score is 9.8.
How this weakness is prevented
- Architecture and Design Implementation: Define all possible states and handle all unused states through default statements. Ensure that system defaults to a secure state.

Dormakaba Saflok System 6000: Improper Finite State Machines (FSMs) in Hardware Logic
Dormakaba Saflok System 6000 contains a predictable key generation algorithm that allows attackers to derive card access keys from a 32-bit unique identifier. Attackers can exploit the deterministic key generation process by calculating valid access keys using
