Descriptions

The Alcatel A30 device with a build fingerprint of TCL/5046G/MICKEY6US:7.0/NRD90M/J63:user/release-keys contains a hidden privilege escalation capability to achieve command execution as the root user. They have made modifications that allow a user with physical access to the device to obtain a root shell via ADB. Modifying the read-only properties by an app as the system user creates a UNIX domain socket named factory_test that will execute commands as the root user by processes that have privilege to access it (as per the SELinux rules that the vendor controls).

El dispositivo Alcatel A30 con una build de huella dactilar de TCL/5046G/MICKEY6US:7.0/NRD90M/J63:user/release-keys contiene una capacidad de escalado de privilegios oculto para lograr ejecutar comandos como usuario root. Han realizado modificaciones que permiten que un usuario con acceso físico al dispositivo obtenga un shell root mediante ADB. La modificación de las propiedades de solo lectura por parte de una aplicación como usuario del sistema crea un socket de dominio UNIX llamado factory_test que ejecutará comandos como usuario root por medio de procesos que tienen privilegios para acceder a este (según las reglas SELinux que controla el fabricante).
