The MXQ TV Box 4.4.2 Android device with a build fingerprint of MBX/m201_N/m201_N:4.4.2/KOT49H/20160106:user/test-keys contains the Android framework with a package name of android (versionCode=19, versionName=4.4.2-20170213) that contains an exported broadcast receiver application component that, when called, will make the device inoperable. The vulnerable component named com.android.server.SystemRestoreReceiver will write a value of --restore_system\n--locale=<localeto the /cache/recovery/command file and boot into recovery mode. During this process, it appears that when booting into recovery mode, the system partition gets formatted or modified and will be unable to boot properly thereafter. After the device wouldn't boot properly, a factory reset of the device in recovery mode does not regain properly functionality of the device. The com.android.server.SystemRestoreReceiver broadcast receiver app component is accessible to any app co-located on the device and does not require any permission to access. The user can most likely recover the device by flashing clean firmware images placed on an SD card.
