      "value": "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. 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)."

      "value": "Se detect\u00f3 un problema en los dispositivos OnePlus versiones One, X, 2, 3 y 3T. OxygenOS e HydrogenOS son vulnerables a ataques de degradaci\u00f3n. Esto se debe a un \"updater-script\" indulgente en OTAs que no comprueba que la versi\u00f3n actual sea inferior o igual a la de la imagen en cuesti\u00f3n. Las degradaciones pueden ocurrir incluso en cargadores de arranque bloqueados y sin activar un restablecimiento de f\u00e1brica, permitiendo la explotaci\u00f3n 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 actualizaci\u00f3n. Esto es posible porque la transacci\u00f3n de actualizaci\u00f3n no se realiza por medio de TLS (CVE-2016-10370). Adicionalmente, un atacante f\u00edsico puede reiniciar el tel\u00e9fono en la recuperaci\u00f3n y luego usar \"adb sideload\" para empujar la OTA (en OnePlus 3/3T \"Secure Start-up\" debe estar desactivado)."
