CVE-2018-14986

Estado: ModificadaAlta (7.5)—

The Leagoo Z5C Android device with a build fingerprint of sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:user/release-keys contains a pre-installed app with a package name of com.android.messaging (versionCode=1000110, versionName=1.0.001, (android.20170630.092853-0)) containing an exported content provider named com.android.messaging.datamodel.MessagingContentProvider. Any app co-located on the device can read the most recent text message from each conversation.

Leer descripción completaMostrar menos

That is, for each phone number where the user has either sent or received a text message from, a zero-permission third-party app can obtain the body of the text message, phone number, name of the contact (if it exists), and a timestamp for the most recent text message of each conversation. As the querying of the vulnerable content provider app component can be performed silently in the background, a malicious app can continuously monitor the content provider to see if the current message in each conversation has changed to obtain new text messages.

Cualquier app que esté en el dispositivo puede leer el mensaje de texto más reciente de cada conversación. En otras palabras, para cada número de teléfono al que el usuario haya enviado o recibido un mensaje de texto, una aplicación de terceros sin permisos puede obtener el cuerpo del mensaje de texto, el número de teléfono, el nombre del contacto (si existe) y una marca de tiempo para el mensaje de texto más reciente de cada conversación. Como la consulta del componente de la app de provisión de contenidos puede realizarse silenciosamente en segundo plano, una app maliciosa puede monitorizar continuamente el proveedor de contenidos para comprobar si el mensaje actual en cada conversación ha cambiado para obtener nuevos mensajes de texto."
