While I have no doubt than basically anything from China is probably backdoored (and to the fault of western countries outsourcing manufacturing for cheap labour), what exactly has Huawei done? How do we know that the Cisco equipment also isn't backdoored and if I send a few malformed TCP packets it opens up its control plane on the receiving port? Compared to the last few decades, it seems like a strong hand banning…
Except the agent had a pretty obvious command runner on one of the message handlers. I was a little afraid to ask them whether it was deliberate or just a really incompetently written backup update mechanism.
To be fair, I was looking for arbitrary command execution for my own purposes at the time...
I do get a decent chuckle when I see their OUI in scan results when out and about now. (About ~0.12% of the recorded results in Wigle it seems)
