# Exploit Title: Acronis True Image OEM 19.0.5128 - 'afcdpsrv' Unquoted Service Path
|

# Date: 2019-11-11

# 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
|
||
|
||
