So, I'm not familiar with Ubiquity much... they seem fairly new to the scene. I was just reading up on them and came across this:
https://en.wikipedia.org/wiki/Ubiquiti_Networks
"In 2013, it was discovered that there was a security issue in the version of the U-Boot boot loader shipped on Ubiquiti's devices. It was possible to extract the plaintext configuration from the device without leaving a trace using Trivial File Transfer Protocol (TFTP) and an Ethernet cable, revealing information such as passwords.[4]
While this issue is fixed in current versions of Ubiquiti hardware, despite many requests and acknowledging that they are using this GPL-protected application, Ubiquiti refuses to provide the source code for the GNU General Public License (GPL)-licensed U-Boot.[5][6] This made it impossible (in practical terms) for Ubiquiti's customers to fix the issue."
Did you run into this? Was it as bad as it sounds?
