Hotspot Shield Unquoted Service Path Privilege Escalation

Hotspot Shield installs as a service with an unquoted service path. To properly exploit this vulnerability, the local attacker must insert an executable file in the path of the service. Upon service restart or system reboot, the malicious code will be run with elevated privileges.

Mitigation:

Ensure that all services have a fully qualified path with quotes around the path.
