CVE-2023-52104Network attack vector

Service information disclosure via unverified WMS parameters

Published Jan 16, 2024 · Updated Jun 2, 2025

Improper access control in Huawei HarmonyOS 3.0.0, 3.1.0, and 4.0.0 and EMUI 13.0.0 allows remote attackers to obtain service information. The WMS module processes unspecified parameters without first verifying them, but Huawei has not disclosed the affected interface or required validation. CISA assesses network reachability without privileges or user interaction; the record identifies only confidentiality impact, with no integrity or availability effect.
