CVE-2017-8171

Huawei smart phones with software earlier than Vicky-AL00AC00B172D versions have a Factory Reset Protection (FRP) bypass security vulnerability. When re-configuring the mobile phone using the factory reset protection (FRP) function, an attacker can login the Talkback mode and can perform some operations to bypass the Google account verification. As a result, the FRP function is bypassed.

4.6 3.0 MEDIUM
CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N Click to expand
Attack vector (AV:P)
Hands-on access—USB, keyboard, opening the case—not something you do purely over the wire.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
