Name of the Vulnerable Software and Affected Versions Huawei Mate 20 Pro versions prior to 9.1.0.135(C00E133R3P1)

Description The issue is related to improper authorization, where the software fails to properly restrict certain operations of certain privileges. An attacker could trick a user into installing a malicious application before the user enables the student mode function.
