CVE-2021-22410Network attack vector

Authenticated cross-site scripting via insufficient input validation

Published Nov 23, 2021 · Updated Aug 3, 2024

Cross-site scripting in Huawei iMaster NCE-Fabric V100R019C10 allows remote authenticated users to inject client-side script. An undisclosed client module insufficiently validates modified input before incorporating it into browser-rendered content. Exploitation requires logging on to the client and user interaction; script execution can alter or disclose browser-context data and disrupt normal client service.
