Fortitude HTTP 1.0.4.0 Unquoted Service Path Elevation of Privilege

Netgear Genie installs a service called 'Fortitude HTTP' 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. 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.

Mitigation:

Ensure that all services are installed with a fully qualified path name, and that all paths are enclosed in quotation marks.
