Insecure OTA Update Mechanism on OnePlus Devices Increases Attack Surface

CVE-2016-10370 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:P/A:N

An issue was discovered on OnePlus devices such as the 3T. The OnePlus OTA Updater pushes the signed-OTA image over HTTP without TLS. While it does not allow for installation of arbitrary OTAs (due to the digital signature), it unnecessarily increases the attack surface, and allows for remote exploitation of other vulnerabilities such as CVE-2017-5948, CVE-2017-8850, and CVE-2017-8851.
