Hey dudes :)
Content:
a) Problem
b) Affected versions
c) Exploiting
-------------------------------------------------------
A)
The HTML-function is usually activated in hpm_guestbook.cgi, so you can inject every HTML-code inclusive JavaScript.
B)
I don't know, sorry. In my version on a freespace hoster I couldn't see the version.
C)
You can post the following Proof of Concept code to understand the problem:
<script language="JavaScript">alert("This guestbook is insecure: " + document.location.href);</script>
If you're logged in as the admin of the guestbook and you want to see the posts you'll see that the password of your account is in the URL of hpm_login.cgi and the code shows you the URL. If you like you can make a code which sends the URL to a PHP-Script
. Then you can get the password of the admin.
You have to keep your code in one line!
