The firmware update functionality does not verify the authenticity of the supplied firmware update files. This allows attackers to flash malicious firmware update files on the device. Initial analysis of the firmware update functionality does not show any cryptographic checks (e.g. digital signature checks) on the supplied firmware update files. Furthermore, ESP32 security features such as secure boot are not used.
