CVE-2026-40436Network attack vector

Account takeover via underprotected user-list interface

Published Apr 13, 2026 · Updated Apr 13, 2026

Improper privilege management in ZTE ZXEDM iEMS ElasticNet_UME_R32_V16.25.42.04 allows remote authenticated users to reset passwords. The cloud EMS portal fails to enforce access control on its user-list acquisition function, exposing every user's account information for password-reset requests. Low-privileged access and user interaction are required; successful exploitation enables account takeover and unauthorized management operations.
