CVE-2025-7116Public exploitNetwork attack vector

Service crash via unbounded ssid copy

Published Jul 7, 2025 · Updated Jul 7, 2025

Buffer overflow in UTT 进取 750W firmware 3.2.2-191225 and earlier allows remote authenticated users to crash the router via a crafted ssid. The Fast_wireless_conf handler passes the ssid value to strcpy at offset 40 without bounding the copy to the destination buffer. The published request uses HTTP Digest administrator credentials, and an oversized value triggers a stack overflow that interrupts router service.
