CVE-2017-5948 (GCVE-0-2017-5948)

Vulnerability from cvelistv5 – Published: 2017-05-11 18:00 – Updated: 2024-08-05 15:18
VLAI
Summary
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).

This is due to a lenient \u0027updater-script\u0027 in OTAs that does not check that the current version is lower than or equal to the given image\u0027s. 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 \u0027adb sideload\u0027 to push the OTA (on OnePlus 3/3T \u0027Secure Start-up\u0027 must be off)."

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).
