  ACROS Security 0patch (0PatchServicex64.exe) Unquoted Service Path Privilege Escalation
  
  
  Vendor: ACROS, d.o.o.
  Product web page: https://www.0patch.com
  Affected version: 2016.05.19.539
  
  Summary: 0patch (pronounced 'zero patch') is a platform for instantly
  distributing, applying and removing microscopic binary patches to/from
  running processes without having to restart these processes (much less
  reboot the entire computer).
  
  Desc: The application suffers from an unquoted search path issue impacting
  the service '0patchservice' for Windows deployed as part of 0patch solution.
  This could potentially allow an authorized but non-privileged local user to
  execute arbitrary code with elevated privileges on the system. A successful
  attempt would require the local user to be able to insert their code in the
  system root path undetected by the OS or other security applications where
  it could potentially be executed during application startup or reboot. If
  successful, the local user’s code would execute with the elevated privileges
  of the application.
  
  Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
   Microsoft Windows 7 Professional SP1 (EN)
