Tesla Telematics Control Unit (TCU) firmware prior to v2025.14 contains an authentication bypass vulnerability. The TCU runs the Android Debug Bridge (adbd) as root and, despite a “lockdown” check that disables adb shell, still permits adb push/pull and adb forward. Because adbd is privileged and the device’s USB port is exposed externally, an attacker with physical access can write an arbitrary file to a writable location and then overwrite the kernel’s ueventhelper or /proc/sys/kernel/hotplug entries via ADB, causing the script to be executed with root privileges.

Securing externally available CAN wires can easily allow physical access to the CAN bus, allowing possible injection of specially formed CAN messages to control remote start functions of the vehicle.  Testing completed on Tesla Model 3 vehicles with software version v11.1 (2023.20.9 ee6de92ddac5). This issue affects Model 3: With software versions from 2023.Xx before 2023.44.

Tesla Wall Connector Content-Length Header Improper Input Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Tesla Wall Connector devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the parsing of the HTTP Content-Length header.
