Vulnerability
HUAWEI Mate 20 smart phones with versions earlier than 10.0.0.175(C00E70R3P8) have an insufficient authentication vulnerability. The bug allows a local attacker with high privilege to execute a specific command, bypassing proper authentication checks.
Exploitation
A local attacker must have high privileges on the device. With those privileges, the attacker can execute a specific command, likely through a command-line interface or a system utility, to trigger the vulnerability.
Impact
Successful exploitation may cause information leak (unauthorized disclosure of sensitive data) and compromise the availability of the smart phones, potentially leading to denial of service or system instability.
Mitigation
Huawei has released software update version 10.0.0.175(C00E70R3P8) to fix this vulnerability. Users should upgrade their devices to this version or later. No workarounds are documented.
