CVE-2023-49242Network attack vector

Unauthenticated service data disclosure via exposed broadcasts

Published Dec 6, 2023 · Updated Aug 2, 2024

Information disclosure in affected Huawei HarmonyOS and EMUI releases allows remote attackers to read confidential service data via broadcasts. Huawei identifies the locus only as the running management module and has not disclosed which broadcast is exposed or how access control fails. NVD describes an unauthenticated, network-reachable path requiring no user interaction, while published sources report confidentiality impact only.
