CVE-2025-14141Public exploitNetwork attack vector

Authenticated router crash via unchecked pools copy

Published Dec 6, 2025 · Updated Dec 8, 2025

Buffer overflow in UTT 进取 520W 1.7.7-180627 allows remote authenticated users to crash the router through a crafted pools value. In /goform/formArpBindConfig, webConfigArpBindConfig passes the pools input to strcpy without checking the destination buffer size. Access requires valid management credentials, and the published proof of concept demonstrates a denial-of-service crash rather than code execution.
