Published May 26, 2023 · Updated Jan 15, 2025

Improper application authentication in Huawei HarmonyOS 3.0.0 and 3.1.0 and EMUI 13.0.0 allows attackers to interrupt MeeTime. The hwKitAssistant online authentication function accepts an application's identity without strict verification, allowing an unverified application to interfere with authenticated feature access. The public record does not disclose the request format or whether a malicious local application is required; reported impact is limited to feature availability.
