Estado: ModificadaAlta (8.8)—

**EN DISPUTA** etc/ObjectList en Metview 4.7.3 no valida cadenas antes de iniciar el programa especificado por la variable de entorno BROWSER. Esto permite que atacantes remotos lleven a cabo ataques de inyección de argumentos mediante una URL manipulada. NOTA: un tercero ha indicado que el código que accede a esta variable de entorno no está activado en el producto publicado.
