CVE-2020-9073

Student mode bypass via insufficient identity validation

Published May 15, 2020 · Updated Aug 4, 2024

Improper authentication in Huawei P20 before 10.0.0.156(C00E156R1P4) allows physically proximate attackers to bypass Student mode limits. Huawei has not published the affected component or the identity-validation operation that accepts the physical user's action without sufficient verification. Physical access to the handset is required, and the documented consequence is limited to bypassing Student mode restrictions.
