Vulnerability: Replay Attack on Nissan Sylphy Classic 2021 Remote Keyfob System

CVE-2023-33281 · MEDIUM Severity

CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

The remote keyfob system on Nissan Sylphy Classic 2021 sends the same RF signal for each door-open request, which allows for a replay attack. NOTE: the vendor's position is that this cannot be reproduced with genuine Nissan parts: for example, the combination of keyfob and door handle shown in the exploit demonstration does not match any technology that Nissan provides to customers.
