CVE-2021-22331Network attack vector

Service disruption via insufficient application-request validation

Published Apr 28, 2021 · Updated Aug 3, 2024

JavaScript injection in Huawei P30 allows attackers to disrupt normal service via a malicious application request. The affected module insufficiently validates input in specific application requests and consequently launches injected JavaScript. Exploitation requires delivery of such a request to that module; Huawei has not disclosed the module, request format, or a more specific operational consequence.
