CVE-2022-34737Network attack vector

Data exposure and modification via incorrect permissions

Published Jul 11, 2022 · Updated Aug 3, 2024

Incorrect permission assignment in HarmonyOS 2.0 and affected EMUI releases allows remote attackers to read and modify protected data. The application security module assigns permissions incorrectly, but Huawei has not disclosed the affected permission, protected resource, or triggering input. Network access without authentication is sufficient; the published impact is limited to confidentiality and integrity.
