CVE-2021-22372Network attack vector

Unauthenticated service-data disclosure

Published Jun 30, 2021 · Updated Aug 3, 2024

Logic bypass in Huawei EMUI 11.0.0 and Magic UI 4.0.0 allows remote attackers to read service data via network requests. Huawei has not published the affected component, the security check that is bypassed, or the input that triggers the bypass. Network access without authentication is sufficient according to NVD's assessment, but the affected service and exposed data remain undisclosed.
