EyeLock Myris 3.3.2 SDK Service Unquoted Service Path Privilege Escalation

Title: EyeLock Myris 3.3.2 SDK Service Unquoted Service Path Privilege Escalation
Advisory ID: ZSL-2016-5355
Type: Local
Impact: Privilege Escalation
Risk: (2/5)
Release Date: 10.08.2016
myris® provides unparalleled security, is portable, lightweight and is as easy as looking in a mirror. Use myris to quickly and easily enroll users for EyeLock’s access control products or to grant users access to corporate domain environments within seconds—users never have to type their username and password again.
The application suffers from an unquoted search path issue impacting the service 'MyrisService' for Windows deployed as part of Myris solution. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system. A successful attempt would require the local user to be able to insert their code in the system root path 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.
