Re: Universal Website Hijacking by Exploiting Firewall Content Filtering Features + SonicWALL firewalls 0day

Hi Fionnbharr,

Well, that's fair enough. tbh, I couldn't find older examples, but
this is one of the points of sending a post to the lists: other people
can review it and give feedback. I just sometimes wished people were
more constructive on FD.

Regarding the paper, well, it can be useful for people who want to
find a similar issue in their firewall/proxy appliances. Don't you
think?

No need to call anyone names IMO. And please, why do people keep
attacking Kaminsky? He has greatly contributed to the infosec
community so please give him some credit!

Thanks for your email anyway. Perhaps, you could have expressed
yourself in a less aggressive/more constructive manner?

Regards,
ap.
