CVE-2020-1791

Unauthorized desktop access via ADB command sequence

Published Feb 18, 2020 · Updated Aug 4, 2024

Improper authorization in Huawei Mate 20 before 10.0.0.185(C00E74R3P8) allows physically proximate attackers to access a locked host desktop. Huawei describes a logic-judgment error but has not disclosed the affected component or the precise authorization decision that accepts the ADB sequence. Exploitation requires command execution in ADB mode from a guest context; the reported consequence is limited to switching into the host user's desktop.
