CVE-2023-44113Network attack vector

Unauthenticated service-data disclosure via unchecked DFR APIs

Published Dec 6, 2023 · Updated Oct 10, 2024

Missing authorization in Huawei DFR APIs allows remote attackers to read service data from affected HarmonyOS and EMUI releases. The DFR module exposes APIs without performing required permission checks before allowing access to confidentiality-sensitive service information. Network access is sufficient without authentication or user interaction on HarmonyOS 2.1.0, 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0.
