CVE-2022-39010Network attack vector

Network-information disclosure via HwChrService permission control

Published Sep 16, 2022 · Updated Aug 3, 2024

Permission-control failure in Huawei HarmonyOS 2.0 and EMUI 12.0.0 allows attackers to read user network information. Huawei identifies improper permission control in HwChrService but has not published the affected interface or the missing authorization check. A third-party app running on the device is the published gate, and the disclosed consequence is limited to exposure of user network information.
