Estado: ModificadaAlta (7)—

Se ha descubierto un problema de elemento de ruta de búsqueda no controlado en Vyaire Medical CareFusion Upgrade Utility, empleado en sistemas Windows XP, en versiones 2.0.2.2 y anteriores. Una explotación con éxito de esta vulnerabilidad requiere que el usuario local instale un DLL malicioso en la máquina objetivo. La aplicación carga el DLL y proporciona al atacante acceso al mismo nivel de privilegios que la aplicación.
