You can spoof any IP. The question is do you want the return traffic.

Subject: Session & IP Spoofing

Hi,

I've found a vulnerability in a Web App which
gave me via an XSS the sessionID token.

I would like to replay this token. But the
session ID manager (on the server) seems to look
also to IP adresses.

So my question is: Is there a way to spoof my ip
address in order to replay the sessionID??

Like:
http://www.tutu.com/toto.php?sessionid=32443243
and some how spoof of my IP?!

If I replay the sessionid from my machine or an
other machine behind my NAT (same outside IP) it
works!!

Thanks a lot for your help
