The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations. This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code. Successful exploitation simplify an attacker to predict the next valid rolling code, granting unauthorized access to the vehicle.
Advisories

No advisories yet.

Fixes

Solution

* Increase entropy: The random component of the code must be significantly larger. A 16-bit keyspace is insecure by modern standards. A minimum of 64 bits of entropy would make a brute-force attack computationally infeasible.


Workaround

No workaround given by the vendor.
