  # Exploit Title: Realtek High Definition Audio Driver - Unquoted Service Path Privilege Escalation # Date: 10/19/2016 # Exploit Author: Joey Lane # Version: 6.0.1.6730 # Tested on: Windows 7 Professional The Realtek High Definition Audio Driver installs a service with an unquoted service path. This enables a local privilege escalation vulnerability.To exploit this vulnerability, a local attacker can insert an executable file in the path of the service. Rebooting the system or restarting the service will run the malicious executable with elevated privileges. This was tested on version 6.0.1.6730, but other versions may be affected as well. --------------------------------------------------------------------------- C:\>sc qc RtkAudioService [SC] QueryServiceConfig SUCCESS   SERVICE_NAME: RtkAudioService TYPE : 10WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL: 1 NORMAL BINARY_PATH_NAME : C:\Program Files\Realtek\Audio\HDA\RtkAudioService64.exe LOAD_ORDER_GROUP : PlugPlay TAG: 0 DISPLAY_NAME : Realtek Audio Service DEPENDENCIES : 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.
