  eForum is prone to an arbitrary-file-upload vulnerability because the application fails to adequately sanitize user-supplied input.
  
  An attacker can exploit this issue to upload arbitrary code and run it in the context of the webserver process.
  
  eForum 1.1 is vulnerable; other versions may also be affected. 
  
  if (isset($_FILES)) { //upload attachments
  ...snip...
   $invalidFileTypes = array('php', 'php3', 'php4', 'php5', 'exe', 'dll', 'so', 'htaccess');
   $uploaddir = $eforum->path.'/upload';
   $upfiles = $_FILES['efattachment'];
   foreach ($upfiles['name'] as $idx => $upname) {
   if ($upname != '') {
   $source = $upfiles['tmp_name'][$idx];
   if (is_uploaded_file($source)) {
   if (in_array($fmanager->FileExt($upname), $invalidFileTypes)) { continue; }
