An unprivileged remote attacker on the adjacent network, can download most system files, leading to serious critical information disclosure. Also, some TV models and/or FW versions may expose the webserver with the entire filesystem accessible on another port. For example, nmap scan for all ports run directly from the TV model U43P6046 (Android 8.0) showed port 7983 not mentioned in the original CVE description, but containing the same directory listing of the entire filesystem. This webserver is bound (at least) to localhost interface and accessible freely to all unprivileged installed apps on the Android such as a regular web browser. Any app can therefore read any files of any other apps including Android system settings including sensitive data such as saved passwords, private keys etc."},{"lang":"es","value":"Una vulnerabilidad en la serie TCL Android Smart TV V8-R851T02-LF1 versiones V295 y por debajo y V8-T658T01-LF1 versiones V373 y por debajo de TCL Technology Group Corporation, permite a un atacante en la red adyacente navegar y descargar arbitrariamente archivos confidenciales a través de un servidor web no seguro ejecutándose en el puerto 7989 que enumera todos los archivos y directorios. Un atacante remoto no privilegiado en la red adyacente puede descargar la mayoría de los archivos del sistema, conllevando a una divulgación de información crítica seria. Además, algunos modelos de televisión y/o versiones FW pueden exponer el servidor web con todo el sistema de archivos accesible en otro puerto. Por ejemplo, la exploración de nmap para todos los puertos ejecutados directamente desde el modelo de TV U43P6046 (Android 8.0) mostró el puerto 7983 no mencionado en la descripción original de CVE, pero que contenía el mismo listado de directorios de todo el sistema de archivos. Este servidor web está vinculado (al menos) a la interfaz del host local y es accesible libremente a todas las aplicaciones instaladas sin privilegios en el Android, como un navegador web normal.
