This vulnerability is also an issue on the popular DLink DI-614+ (which I
think is based upon the Longshine product). I was able to grab config.img
and also extract the "admin" password from it. This was confirmed with
firmware version 2.03 dated 9/10/2002.

On the DLink product, you can only perform this from the "LAN-side" of the
device in the default configuration.

DLink has version 2.10 available, dated 11/25/2002, but I have not tried
it yet.
