CVE-2020-9066

Authentication bypass via malicious plug-in installation

Published Mar 26, 2020 · Updated Aug 4, 2024

Improper authentication in Huawei Honor V30 Pro firmware before 10.0.1.169(C00E166R4P1) allows attackers to perform unauthorized operations. An unspecified application fails to authenticate certain plug-in-triggered operations, but Huawei has not disclosed the affected component or checks. Exploitation requires tricking a user into installing a malicious plug-in; Huawei defines the consequence only as unauthorized operations.
