During startup, the AM335x secure boot feature decrypts and executes firmware. Secure boot can be bypassed by starting with certain commands to the USB serial port. Although a power cycle occurs, this does not completely reset the chip: memory contents are still in place. Also, it restarts into a boot menu that enables XMODEM upload and execution of an unsigned QNX IFS system image, thereby completing the bypass of secure boot. Moreover, the attacker can craft custom IFS data and write it to unused memory to extract all memory contents that had previously been present. This includes the original firmware and sensitive information such as Wi-Fi credentials."}, {"lang": "es", "value": "Puede lograrse la omisi\u00f3n del arranque seguro y la extracci\u00f3n de memoria en dispositivos Neato Botvac Connected 2.2.0.
