Summary
Smart TV Box fails to restrict access permissions
Details
Smart TV Box provided by KDDI CORPORATION enables access to Android Debug Bridge via port 5555/TCP of LAN side interface. When a cable television provider sets up Smart TV Box at an individual residence, direct access from outside to the LAN side interface of Smart TV Box is disabled. However if the original setting is changed later, for example, LAN side interface connection to internet directly is enabled, access to Android Debug Bridge via port 5555/TCP of LAN side interface becomes enabled. As a result, arbitrary operations without users intent becomes possible, and a remote attacker may conduct arbitrary operations on the device. Yoshiki Mori and Masaki Kubo of Cybersecurity Laboratory, National Institute of Information and Communications Technology reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
