      "value": "In SignalRGB versions prior to 1.3.7.0, the \\\\.\\SignalIo device object is created without an explicit SDDL security descriptor and without FILE_DEVICE_SECURE_OPEN. This results in overly permissive default access control, allowing any authenticated local user to obtain a handle to the device and issue privileged IOCTLs."

Esto resulta en un control de acceso predeterminado excesivamente permisivo, permitiendo que cualquier usuario local autenticado obtenga un identificador (handle) para el dispositivo y emita IOCTLs privilegiados."
