I have used UniFi/Ubiquiti network products for quiet some time now. I’ve deployed their hardware at many past customers and used it for most of my home network. Recently, I had to manually update the firmware on my Cloud Key via a shell and did some poking around on it. It seems to just be an ARM device with Debian and some software installed. Since it accepts POE for power and looks pretty innocuous in a network rack, I thought it would be an interesting device to get some of the Kali tool-set to run on.
To start off, here is a link to the official product page. This device is a purpose built “server”, which runs Ubiquiti’s UniFi controller software, is powered over POE, has an SD card slot, and has a simple web interface for managing the device itself. Ubiquiti offers a “cloud” management system as well, allowing network management over the Internet, hence the name Cloud Key. As for hardware specs, it has 2Gb of RAM, 16Gb onboard MMC storage, and a quad-core ARM CPU. There has been some hardware revisions, it seems, and I believe what I have here is a third generation, which includes USB C for external power and a physical power button.
After powering it up and getting SSHed in, I started snooping around the Debian install.

I eventually found some interesting Ubnt-* tools. These are used to do some firmware and service related tasks. It looks like some features are duplicated in different tools.

With all that out of the way, I decided to try to just add the Kali repo and install something from it. First I need to install nano, I guess.
I added the Kali repo, added the gpg key for their repo, updated package lists, then tried to install metasploit.
echo "deb http://http.kali.org/kali kali-rolling main non-free contrib" >> /etc/apt/sources.list
apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 7D8D0BF6
apt update
apt install metasploit-framework
And metasploit works!
With that being a success, there are a few issues that need to be addressed. First, the UniFi controller software is still running, possibly spewing packets to the network, looking for APs and switches. That, along with some other unneeded software, can easily be removed. Two, due to how the onboard MMC storage is partitioned, the root filesystem only has about 1.5G left after the MSF install. I’m sure I can find a way to use other partitions or SD card for storage. I’ll work on that later, since its not breaking anything yet. Three, I need to set up an automatic reverse shell, since the intent is to not be logging into this thing locally. And lastly, some encrypted storage probably wouldn’t be a bad idea as well.
Part two is coming soon…
