Tesla Wall Connector bootloader bypasses the firmware downgrade ratchet | Hacker News

Researchers found a bootloader-based bypass in Tesla Wall Connector that can defeat its firmware downgrade protection.

The issue emerged after discussions about charger firmware behavior, Wi-Fi quirks, and how much control users have over software updates.

If exploited, the bypass could let owners or attackers roll back to older firmware versions despite Tesla’s anti-downgrade safeguards.

The finding raises security and device-control concerns for Tesla Wall Connector deployments.
