  [-] Vulnerability explanation:
  
  The vulnerable code is located into /ajaxfilemanager/ajax_create_folder.php:
  
  11.	@ob_start();
  12.	displayArray($_POST);
  13.	writeInfo(@ob_get_clean());
  
  this script start the output buffering at line 11 and then call the 'displayArray'
  function that simply displays the $_POST array content with the print_r() function,
  and finally at line 13 is called the 'writeInfo' function using the current buffer
  contents as parameter (that is the $_POST array content). Now look at the 'writeInfo'
  function body defined into /ajaxfilemanager/inc/function.base.php:
  
  228.	function writeInfo($data, $die = false)
  229.	{
  230.	  $fp = @fopen(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'data.php', 'w+');
  231.	  @fwrite($fp, $data);
  232.	  @fwrite($fp, "\n\n" . date('d/M/Y H:i:s') );
  233.	  @fclose($fp);
  
  It writes the $data paramater into a file called 'data.php' without any check,
  so an attacker could be able to inject and execute arbitrary PHP code.
