Remote code execution via unchecked param copy

Published Dec 4, 2025 · Updated Dec 5, 2025

Buffer overflow in H3C Magic B0 100R002 and earlier allows remote authenticated users to execute code through a crafted WLAN MAC-list request. EditWlanMacList in /goform/aspForm copies the param field without a length limit, overflowing its destination buffer. A low-privileged web-management session and network reachability are required; exploitation can crash the router or execute code.
