CVE-2025-4446

Authenticated code execution via oversized SSID parameter

Published May 9, 2025 · Updated May 9, 2025

Buffer overflow in H3C Mini GR-5400AX 100R008 allows remote authenticated users on the local network to execute code. The Edit_List_SSID function at /goform/aspForm copies the param request-body field into a fixed-size destination without verifying its length. Access to the web management interface and low privileges are required; successful exploitation can also crash the router and interrupt service.
