Recently traded a few emails with a person who showed me some information at least interesting:
Good! Was to warn that there already exists a tool able to exploit the vulnerability. More info here: http://ptsec.info/forum/showthread.php?21-Vulnerabilidade-que-afecta-Thomson-com-WPS-implementado (have to be registered in order to be able to see the forum topic) or here (in English): http://www.backtrack-linux.org/forums/showthread.php?t=47519&p=213572&viewfull=1#post213572
I have not had time to read everything and test, but information-crossing is an interesting topic.
