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)."}, {"lang": "es", "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)."}], "lastModified": "2019-10-03T00:03:26.223", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:oneplus:oxygenos:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8189780A-EA20-4B96-A625-48D12948B3F2"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:oneplus:oneplus_2:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "332B048C-6522-41A7-9DAB-834FBFCA3C00"}, {"criteria": "cpe:2.3:h:oneplus:oneplus_3:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "E6B1891E-38B0-42C5-89D3-3DC12217F087"}, {"criteria": "cpe:2.3:h:oneplus:oneplus_3t:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "4C7E02CB-9EAC-4BFD-8CCC-337610E1CCEE"}, {"criteria": "cpe:2.3:h:oneplus:oneplus_one:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "8B8AD37A-7539-4F16-8AC2-2556035B0DE2"}, {"criteria": "cpe:2.3:h:oneplus:oneplus_x:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "C0A390FA-9B56-4645-991D-5E9CB16966B9"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "cve@mitre.org"}
