Subject: [Bulk] Re: D-Link DSL routers authentication
	bypass

I found this vulnerability for my job last March. I immediately tried to 
contact D-Link since i didn't trust the e-mail for ordinary technical 
support. At the beginning of May I managed to submit to D-Link the 
vulnerability and I received an answer as you find in the advisory.

Bye
