CVE-2023-44097Network attack vector

Device serial-number disclosure via improper permission checks

Published Oct 11, 2023 · Updated Sep 18, 2024

Information disclosure in Huawei HarmonyOS 2.0.1 and 3.0.0 and EMUI 12.0.1 and 13.0.0 allows remote attackers to read device serial numbers. The device-serial-number access path applies permissions incorrectly, but Huawei has not identified the responsible component, API, or failed check. Network access requires no privileges or user interaction, and the reported consequence is limited to device-identifying information and service confidentiality.
