RE: RE: Session & IP Spoofing

["pire pire" <pirepire69 () romandie com>]

No I don't care about the return traffic! All I 
need is to sen I GET request with a spoofed IP!

Example:

GET /toto.php?sessionId=123456&transfer=1000
Host: www.toto.com

I just need to send this request to the server 
with the ip adress belonging to the sessionID 
I've got throuh my XSS!


So how do you do that?


Thanks for your help

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

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
