Remotely compromise devices by using bugs in Marvell Avastar Wi-Fi

That’s why this bug is so cool and provides an opportunity to exploit devices literally with zero-click interaction at any state of wireless connection (even when a device isn’t connected to any network). For example, one can do RCE in just powered-on Samsung Chromebook. So just to summarize:

  1. It doesn’t require any user interaction.
  2. It can be triggered every 5 minutes in case of GNU/Linux operating system.
  3. It doesn’t require the knowledge of a Wi-Fi network name or passphrase/key.
  4. It can be triggered even when a device isn’t connected to any Wi-Fi network, just powered on.

In this research, I used ALFA networks wireless adapter in the monitor mode, which is based on Realtek 8187 wireless chipset. The exploit can be implemented with python Scapy framework. For some reason, Ubuntu GNU/Linux distrubution isn’t good enough to inject Wi-Fi frames fast, so it is better to use Kali.
