Shockro,

The danger is also in variables. Pretend that I get you to click on this
link from within your custom intranet mail app.

example.com">http://intranet.example.com/mailbox.asp?action=forward&item=all&recipient=badguyexample.com

It would forward all of your mail to badguyexample.com. This would work
because you already have a session with mailbox.asp.

Of course mailbox.asp is fake but you get the idea.
