CVE-2020-9073

Estado: ModificadaBaja (2.4)—

Huawei P20 smartphones with versions earlier than 10.0.0.156(C00E156R1P4) have an improper authentication vulnerability. The vulnerability is due to that when an user wants to do certain operation, the software insufficiently validate the user's identity. Attackers need to physically access the smartphone to exploit this vulnerability. Successful exploit could allow the attacker to bypass the limit of student mode function.
