Remote confidentiality impact via communication logic error
Published Apr 11, 2022 · Updated Aug 4, 2024
Service logic error in the communication module in Huawei HarmonyOS 2.0 allows remote attackers to affect data confidentiality via network requests. The vendor describes a service logic error in the communication module but does not disclose the faulty operation or interface that processes untrusted input. The advisory provides no authentication or interaction prerequisite beyond network reachability, and the reported consequence is limited to possible confidentiality impact.
