CVE-2023-49244Network attack vector

Service data disclosure via multi-user permission errors

Published Dec 6, 2023 · Updated Aug 2, 2024

Permission errors in HarmonyOS 2.1.0, 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allow remote attackers to read service data. Huawei has not published the affected interface or the incorrect permission operation performed by the multi-user module. Network reachability without authentication or user interaction is sufficient, and the reported consequence is limited to service confidentiality.
