The Remote Keyless Entry (RKE) receiving unit on certain Mazda vehicles through 2020 allows remote attackers to perform unlock operations and force a resynchronization after capturing three consecutive valid key-fob signals over the radio, aka a RollBack attack. The attacker retains the ability to unlock indefinitely.
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
