CVE-2023-49240Network attack vector

Unauthenticated access to launcher service data

Published Dec 6, 2023 · Updated Aug 2, 2024

Unauthorized access in affected Huawei HarmonyOS and EMUI launcher modules allows remote attackers to disclose service data over a network.

No privileges or user interaction are required; the listed HarmonyOS 2.0.0, 3.0.0, 3.1.0, and 4.0.0 and EMUI 11.0.1, 12.0.0, and 13.0.0 releases expose service confidentiality.
