CVE-2017-5948

Estado: ModificadaMedia (5.9)—

An issue was discovered on OnePlus One, X, 2, 3, and 3T devices. OxygenOS and HydrogenOS are vulnerable to downgrade attacks. This is due to a lenient 'updater-script' in OTAs that does not check that the current version is lower than or equal to the given image's. Downgrades can occur even on locked bootloaders and without triggering a factory reset, allowing for exploitation of now-patched vulnerabilities with access to user data. This vulnerability can be exploited by a Man-in-the-Middle (MiTM) attacker targeting the update process.

Leer descripción completaMostrar menos

This is possible because the update transaction does not occur over TLS (CVE-2016-10370). In addition, a physical attacker can reboot the phone into recovery, and then use 'adb sideload' to push the OTA (on OnePlus 3/3T 'Secure Start-up' must be off).

Esto se debe a un \"updater-script\" indulgente en OTAs que no comprueba que la versión actual sea inferior o igual a la de la imagen en cuestión. Las degradaciones pueden ocurrir incluso en cargadores de arranque bloqueados y sin activar un restablecimiento de fábrica, permitiendo la explotación de las vulnerabilidades ahora parcheadas con acceso a los datos del usuario. Esta vulnerabilidad puede ser explotada por un atacante de tipo Man-in-the-Middle (MiTM) que se dirija al proceso de actualización. Esto es posible porque la transacción de actualización no se realiza por medio de TLS (CVE-2016-10370). Adicionalmente, un atacante físico puede reiniciar el teléfono en la recuperación y luego usar \"adb sideload\" para empujar la OTA (en OnePlus 3/3T \"Secure Start-up\" debe estar desactivado)."
