=====================================================  
  
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.
