Unauthenticated window-module information disclosure

Published Apr 8, 2024 · Updated Mar 28, 2025

Improper access control in Huawei HarmonyOS 4.0.0 allows remote attackers to read window-module information over a network. Huawei has not published the permission check that fails, the request or API that reaches it, or the information exposed by the window module. The published network assessment requires neither authentication nor user interaction, but the available advisories do not identify the affected service or device configuration.
