Local service-data disclosure via permission verification failure
Published Aug 8, 2024 · Updated Aug 9, 2024
Access-control failure in Huawei HarmonyOS 3.1.0, 4.0.0, and 4.2.0 and EMUI 13.0.0 and 14.0.0 allows local users to read service data. Huawei identifies the content sharing pop-up module but has not disclosed the specific permission check or operation that mishandles protected content. Exploitation requires local access, needs no prior privileges or user interaction, and affects confidentiality without reported data modification or service interruption.
