漏洞代码：第42行
if(isset($_FILES["File1"]))
  {
  if(isset($_POST["inpCurrFolder2"]))$currFolder=$_POST['inpCurrFolder2']; //目录可以构造magic_quotes_gpc=off时可写任意文件
  if(isset($_REQUEST["inpFilter"]))$ffilter=$_REQUEST["inpFilter"];

  if($MaxFileSize && ($_FILES['File1']['size'] > $MaxFileSize))
{
$sMsg = "The file exceeds the maximum size allowed.";
}
  else if(!isTypeAllowed($_FILES['File1']['name']))
{
$sMsg = "The File Type is not allowed.";
}
  else if (move_uploaded_file($_FILES['File1']['tmp_name'], $currFolder."/".basename($_FILES['File1']['name'])))
{
$sMsg = "";
$sUploadedFile=$_FILES['File1']['name'];
@chmod($currFolder."/".basename($_FILES['File1']['name']), 0644);
}

closedir($handle);
