Descriptions

An issue was discovered in the Espressif ESP32 mask ROM code 2016-06-08 0 through 2. Lack of anti-glitch mitigations in the first stage bootloader of the ESP32 chip allows an attacker (with physical access to the device) to read the contents of read-protected eFuses, such as flash encryption and secure boot keys, by injecting a glitch into the power supply of the chip shortly after reset.

Se descubrió un problema en el código ROM de la máscara de Espressif ESP32 08-06-2016 desde 0 hasta 2. La falta de mitigaciones contra fallos en el cargador de arranque de la primera etapa del chip ESP32 permite a un atacante (con acceso físico al dispositivo) leer el contenido de eFuses protegidos contra lectura, tales como el cifrado flash y las claves de arranque seguras, al inyectar un fallo en la fuente de alimentación del chip poco después del reinicio.
