CVE-2021-37112Network attack vector

Firmware disclosure via externally controlled system settings

Published Jan 3, 2022 · Updated Aug 4, 2024

External control of system settings in Huawei HarmonyOS 2.0 allows attackers to disclose firmware through the HiSuite module. Huawei identifies the HiSuite module and external control of a system or configuration setting, but does not disclose the specific setting or the incorrect operation applied to it. Network access without authentication is sufficient according to NVD's assessment, and the documented consequence is limited to firmware disclosure.
