I was unfamiliar with Tenda.

Tenda may just rebrand, right? It seems like many chinese brands will either rebrand or have a 'competing' brand with the same internals but different externals. (I have no idea if Tenda does this, I've just seen it previously. Specifically with security cameras)

I wish the authors provided some method for checking this vulnerability other than fw version. It seems like Tenda could just change the password and say "yep! all safe now"

Tenda has been around for quite a few years now. I don't imagine they'll rebrand.

I have an ethernet over power adapter somewhere in a cupboard from perhaps 10 years ago.

Back then it was standard for the admin password to be 'admin'. They'd often even print it on the device itself.

Yes but aren't you supposed to change that one? The problem with the rzadmin is that it will continue to work even after you change the regular admin one...

I am still using their Powerline adapters and FWIW they have been very reliable.

Tenda is very popular in Asia, several ISPs use them as their default routers.

My ex used to work in their sales department lol. But I'd seen them anyway, in the context of cheap unmanaged switches on Amazon. They are not a state owned company or anything so I doubt this is anything too nefarious, likely just absolutely not giving a crap about quality.

There's claims of it being "the first home-grown router and wireless network device manufacturer in China".

I’m in the USA and have a Tenda WiFi usb stick. Not as popular as other brands but they are around

It is probably just a brand, like many others, and based on a reference design from the OEM.

I have a small Tenda 5-port gigabit dumb switch. It uses the same switch chip as this TP-Link, just with different branding; even the "SG105" model number is the same:
