Er not quite. That's a list of devices that could have the problem, if
somebody has installed the third party DD-WRT firmware onto it. Not the same
thing, really.

It's also interesting that few of the sites that discuss the exploit
mention that it only works if the attacker can guess the router's IP.

While there may be defaults that a decent percentage of users use,
DD-WRT firmware tends to be installed by more technical users, and few
of the techies that I know use 192.168.(0|1|100).1, using an even
moderately unique subnet will largely neuter the primary attack vectors.
