Waves MaxxAudio, as installed on Dell laptops, adds a "WavesSysSvc" Windows service with File Version 1.1.6.0. This service has a vulnerability known as Unquoted Service Path. This could potentially allow an authorized but non-privileged local user to execute arbitrary code with elevated privileges on the system.
