Descriptions
The ZTE Blade Vantage Android device with a build fingerprint of ZTE/Z839/sweet:7.1.1/NMF26V/20180120.095344:user/release-keys, the ZTE Blade Spark Android device with a build fingerprint of ZTE/Z971/peony:7.1.1/NMF26V/20171129.143111:user/release-keys, the ZTE ZMAX Pro Android device with a build fingerprint of ZTE/P895T20/urd:6.0.1/MMB29M/20170418.114928:user/release-keys, and the ZTE ZMAX Champ Android device with a build fingerprint of ZTE/Z917VL/fortune:6.0.1/MMB29M/20170327.120922:user/release-keys contain a pre-installed platform app with a package name of com.android.modem.service (versionCode=25, versionName=7.1.1; versionCode=23, versionName=6.0.1) that exports an interface to any app on co-located on the device. Using the exported interface of the com.android.modem.service app, any app can enable and obtain certain log files (modem and logcat) without the appropriate corresponding access permissions. The modem logs contain the phone number and full text body of incoming and outgoing text messages in binary format. In addition, the modem log contains the phone numbers for both incoming and outgoing phone calls. The system-wide logcat logs (those obtained via the logcat binary) tend to contain sensitive user data. Third-party apps are prevented from directly reading the system-wide logcat logs. The capability to read from the system-wide logcat logs is only available to pre-installed system apps and platform apps. The modem log and/or logcat log, once activated, get written to external storage (SD card). An app aware of this vulnerability can enable the logs, parse them for relevant data, and exfiltrate them from the device. The modem log and logcat log are inactive by default, but a third-party app with no permissions can activate them, although the app will need to be granted the READ_EXTERNAL_STORAGE permission to access them.
El dispositivo Android ZTE Blade Vantage con una huella digital de ZTE/Z839/sweet:7.1.1/NMF26V/20180120.095344:user/release-keys, el dispositivo Android ZTE Blade Spark con una huella digital de ZTE/Z971/peony:7.1.1/NMF26V/20171129.143111:user/release-keys, el dispositivo Android ZTE ZMAX Pro con una huella digital de ZTE/P895T20/urd:6.0.1/MMB29M/20170418.114928:user/release-keys y el dispositivo Android ZTE ZMAX Champ con una huella digital de ZTE/Z917VL/fortune:6.0.1/MMB29M/20170327.120922:user/release-keys contienen una app de plataforma preinstalada con un nombre de paquete com.android.modem.service (versionCode=25, versionName=7.1.1; versionCode=23, versionName=6.0.1) que exporta una interfaz a cualquier app ubicada en el dispositivo. Mediante la interfaz exportada de la app com.android.modem.service, cualquier app puede habilitar y obtener ciertos archivos de registro (modem y logcat) sin los correspondientes permisos de acceso apropiados. Los registros modernos contienen el número de teléfono y el cuerpo de texto completo de los mensajes de texto entrantes y salientes en formato binario. Además, el registro modem contiene los números de teléfono para las llamadas telefónicas entrantes y salientes. Los registros logcat del sistema (los que se obtienen mediante el binario logcat) suelen contener datos sensibles de usuario. Las aplicaciones de terceros no pueden leer directamente los registros logcat del sistema. La capacidad de leer desde los registros logcat del sistema solo está disponible para las apps del sistema preinstaladas y las apps de la plataforma. El registro modem y/o el logcat, una vez activados, se escriben en el almacenamiento externo (tarjeta SD). Una app que sea consciente de esta vulnerabilidad puede habilitar los registros, analizarlos en busca de datos relevantes y exfiltrarlos desde el dispositivo. Por defecto, los registros modem y logcat están inactivos, pero una app de terceros sin permisos puede activarlos, aunque la app tendrá que contar con el permiso READ_EXTERNAL_STORAGE para acceder a ellos.
