Reading WEP-Key from Win 2000 Network Config

[Marcel Krause <marcel_k () web de>]

Hi!

I'm just playing around with my wireless LAN config in Windows 2000
Professional. There is some security dialog where you can enter your
WEP key in 26 hex digits. You may enter them but not read them because
they are masked with ***. I have a tool which reads the plaintext of
such password boxes but in this case it is not applicable because the
code surrenders as soon as the box receives the focus.

Solution: enter sobe chars that are not hex digits. You will receive
an error message. Select a different one of the 4 av/ keys. It will
be shown in plaintext.

Is this fresh news? Is it exploitable remotly, meaning without sitting
in front of the box?

Yours, Marcel
