CVE-2017-8171 Explained : Impact and Mitigation

Smart phones manufactured by Huawei that have software versions prior to Vicky-AL00AC00B172D are susceptible to a security vulnerability known as Factory Reset Protection (FRP) bypass. This vulnerability allows an attacker to bypass the Google account verification by logging into the Talkback mode and performing certain operations while re-configuring the mobile phone using the FRP function. As a result, the FRP function is successfully bypassed.
