Well.

What's going on is slightly complicated, and not necessarily a big deal, depending. There are eight flaws found in Brother systems, and they all boil down to one fairly serious vulnerability. A flaw was discovered in how Brother generates the default system administrator password based on the serial number of the printer: if the serial number of the printer is known, you can reverse engineer the password. And here's the problem: if you have not changed that password, THEN you are vulnerable to all sorts of potential mischief! And that's where all the other flaws come into play.

Now, if you changed the default password when you installed your printer, then you're fine. Nothing to worry about. Everything's great. If you didn't, then you need to change it ASAP and patch your printer right now!

This flaw also affects 59 printer models from Fujifilm, Toshiba, Ricoh, and Konica Minolta. I'm assuming they use either Brother engines or the same algorithm for generating admin passwords.

The flaw affects 689 printers, the article provides a link with all of the models listed. Since the default password was built into the printer's read-only memory, it can't be patched. Brother is changing the way they generate the password. But again, if you've changed the default password, you're good. The other flaws are patchable, I don't know if patches are out yet but I'm sure they will be available soon if not already.
