  #Title: LiteServe 2.81 PASV Command DoS
  #Author: Craig Freyman (@cd1zz)
  #Date: Bug found July 25, 2011 - Vendor approved release August 7, 2011
  #Tested on Windows XP SP3 and Server 2003 SP2
  #Software: http://www.cmfperception.com/liteserve.html
  #Notes: In certain conditions that I could not reproduce reliably, registers were
  #overwritten. There are a number of other FTP commands that exhibit the same behavior.
