The dynamic-registration of the MasterClearReceiver broadcast receiver app component is not protected with the android.permission.MASTER_CLEAR permission during registration, so any app co-located on the device, even those without any permissions, can programmatically initiate a factory reset of the device. A factory reset will remove all user data and apps from the device. This will result in the loss of any data that have not been backed up or synced externally. The capability to perform a factory reset is not directly available to third-party apps (those that the user installs themselves with the exception of enabled Mobile Device Management (MDM) apps), although this capability can be obtained by leveraging an unprotected app component of core Android process."}, {"lang": "es", "value": "El dispositivo Android MXQ TV Box 4.4.2 con una huella digital de MBX/m201_N/m201_N:4.4.2/KOT49H/20160106:user/test-keys contiene el framework de Android con un nombre de paquete android (versionCode=19, versionName=4.4.2-20170213) que registra din\u00e1micamente un componente de app de recepci\u00f3n de transmisiones llamado com.android.server.MasterClearReceiver, en lugar de registrarlo est\u00e1ticamente en el archivo AndroidManifest.xml del paquete core de Android, tal y como se realiza en el c\u00f3digo de Android Open Source Project (AOSP) para Android 4.4.2.
