This app cannot be disabled by the user and the attack can be performed by a zero-permission app. Executing commands as system user can allow a third-party app to video record the user's screen, factory reset the device, obtain the user's notifications, read the logcat logs, inject events in the Graphical User Interface (GUI), and obtains the user's text messages, and more. This vulnerability can also be used to secretly record audio of the user without their awareness on the Oppo F5 device. The pre-installed com.oppo.engineermode app (versionCode=25, versionName=V1.01) has an exported activity that can be started to initiate a recording and quickly dismissed. The activity can be started in a way that the user will not be able to see the app in the recent apps list. The resulting audio amr file can be copied from a location on internal storage using the arbitrary command execution as system user vulnerability. Executing commands as system user can allow a third-party app to factory reset the device, obtain the user's notifications, read the logcat logs, inject events in the Graphical User Interface (GUI), change the default Input Method Editor (IME) (e.g., keyboard) with one contained within the attacking app that contains keylogging functionality, obtain the user's text messages, and more."}, {"lang": "es", "value": "El dispositivo Android Oppo F5 con una huella digital de compilaci\u00f3n OPPO/CPH1723/CPH1723:7.1.1/N6F26Q/1513597833:user/release-keys alberga una aplicaci\u00f3n de plataforma preinstalada con el nombre del paquete com.dropboxchmod (versionCode=1, versionName=1.0) que contiene un servicio exportado llamado com.dropboxchmod.DropboxChmodService que permite que cualquier aplicaci\u00f3n dentro del dispositivo proporcione comandos arbitrarios para ser ejecutados como usuario del sistema. Esta aplicaci\u00f3n no puede ser desactivada por el usuario y el ataque puede ser ejecutado por una aplicaci\u00f3n de cero permisos. La ejecuci\u00f3n de comandos como usuario del sistema puede permitir que una aplicaci\u00f3n de terceros grabe en video la pantalla del usuario, restaure el dispositivo de f\u00e1brica, consiga las notificaciones del usuario, lea los registros de logcat, inyecte eventos en la Interfaz Gr\u00e1fica de Usuario (GUI) y obtenga los mensajes de texto de usuario, y m\u00e1s.
