CVE-2023-33281: Nissan Sylphy Classic 2021 Firmware

Medium severity, CVSS 6.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
