Just last week someone was dealing with a whole Mikrotik network from
a WISP they bought and the fired ex admin had changed all the
passwords. So it’s not just people too lazy to keep track of
passwords. There are all sorts of scenarios. I remember once I
couldn’t get into a Ubiquiti backhaul, after trying every typo I
could think of I finally figured out that I had changed the username
from ubnt to admon instead of admin. And we generally disable the
reset button due to problems with spontaneous false resets.
I remember actually remember leaving Trango radios at trango/trango
for quite awhile because I was so scared of mistyping the new
password and having to send a climber 200 feet up with a laptop.
(obviously you should change the password while the radios are still
on the ground)

Agree 110% …
It does suck re: having to climb a tower to reset a password but
would also think that folks might suddenly be inclined to keep better
track of passwords after having to do so a couple of times ;)

Am I the only one who assumes everything has one or more
backdoors, including my car? There’s the one the
manufacturer knows about, the one the NSA put there, the one
the software engineer put there and didn’t tell his boss
about, the one the Chinese chip maker put there, the one
Fancy Bear put there …

There's no reason for it to be secret, either. If it exists
purely to assist customers who forgot their password, then
there is no reason to both disclose it, and offer the user
the ability to turn it off. As long as there is still a
physical reset method, then any fallout from forgetting a
password ends up on the customer, if they disabled the
ability for it to be reset.
Let's just imagine right now that someone has already built a
bot that is going out, scanning for Trango radios, and
modifying the running code on them. You can argue that some
fault lies with the operator for not properly securing
his/her network, but the root cause of the problem is an
insecure, root account, hard coded into a radio, with a fixed
password, that cannot be disabled.

True and now it’s been disclosed by a security researcher
and this blows up badly on the vendor in my opinion….
makes you wonder what else they are doing in their
software that they are not telling you about - just an
example and not suggesting there’s more in this case

Well, it’s not a secret backdoor if you disclose it.

Different people deploy them different ways … good or
bad …
The biggest problem I have with this is when a vendor
doesn’t disclose this information and that a customer
cannot choose to remove this option if the vendor
insists on putting it in place.

I don't exactly see the problem, especially with
a PTP radio that should only be accessible from
within your network and possibly only from
management subnets/VLANs, too. If it's a public
facing piece of equipment like a router, then
sure, I agree.

Totally disagree with this… we would never
let a vendor into our network if there was a
possibility of this. It puts our network at
risk from their stupidity ….
We aggressively look at this when new
products are coming into the network -
realizing that sometimes there’s no way to
detect it but it’s a question we ask, tests
that we run, and hope that our confidence in
this being possible is low.
