BlueDucky 🦆

🚨 CVE-2023-45866 - BlueDucky Implementation (Using DuckyScript) 🔓 Unauthenticated Peering Leading to Code Execution (Using HID Keyboard)

This is an implementation of the CVE discovered by marcnewlin [https://github.com/marcnewlin/hi_my_name_is_keyboard]

Introduction 📢

BlueDucky is a powerful tool for exploiting a vulnerability in Bluetooth devices. By running this script, you can:

1. 📡 Load saved Bluetooth devices that are no longer visible but have Bluetooth still enabled.
2. 📂 Automatically save any devices you scan.
3. 💌 Send a default message ("Hello There") if no payload.txt is present.

I've successfully run this on a Raspberry Pi 4 using the default Bluetooth module. It works against various phones, with an interesting exception for a New Zealand brand, Vodafone.

Installation and Usage 🛠️

Setup Instructions

# update apt
sudo apt-get update
sudo apt-get -y upgrade

# install dependencies from apt
sudo apt install -y bluez-tools bluez-hcidump libbluetooth-dev \
                    git gcc python3-pip python3-setuptools \
                    python3-pydbus

# install pybluez from source
git clone https://github.com/pybluez/pybluez.git
cd pybluez
sudo python3 setup.py install

# build bdaddr from the bluez source
cd ~/
git clone --depth=1 https://github.com/bluez/bluez.git
gcc -o bdaddr ~/bluez/tools/bdaddr.c ~/bluez/src/oui.c -I ~/bluez -lbluetooth
sudo cp bdaddr /usr/local/bin/

Running BlueDucky

git clone https://github.com/pentestfunctions/BlueDucky.git
cd BlueDucky
python3 BlueDucky.py

Operational Steps 🕹️

1. On running, it prompts for the target MAC address.
2. Pressing nothing triggers an automatic scan for devices.
3. Devices previously found are stored in known_devices.txt.
4. If known_devices.txt exists, it checks this file before scanning.
5. Executes using payload.txt file.
6. Successful execution will result in automatic connection and script running.

Duckyscript 💻

🚧 Work in Progress:

• Implementing keyboard combinations.
• Current implementations: 6.1 REM (Comment) 6.2 STRING (Text Input)

📝 Example payload.txt:

REM This is a comment and will not run
STRING hello there 123

Enjoy experimenting with BlueDucky! 🌟
