=====================================================
IObit Uninstaller installs a service called 'LiveUpdateSvc' with an
unquoted service path running with SYSTEM privileges.
This could potentially allow an authorized but non-privileged local user
to execute arbitrary code with elevated privileges on the system.
C:\Users\helik>sc qc LiveUpdateSvc
[SC] QueryServiceConfig SUCCESS
SERVICE_NAME: LiveUpdateSvc
TYPE : 10 WIN32_OWN_PROCESS
START_TYPE : 2 AUTO_START
ERROR_CONTROL : 1 NORMAL
BINARY_PATH_NAME : C:\Program
Files\IObit\LiveUpdate\LiveUpdate.exe
LOAD_ORDER_GROUP :
TAG : 0
DISPLAY_NAME : LiveUpdate
DEPENDENCIES :
SERVICE_START_NAME : LocalSystem
====Proof-of-Concept====
To properly exploit this vulnerability, the local attacker must insert
an executable file in the path of the service. Upon service restart or
system reboot, the malicious code will be run with elevated privileges.
