CVE-2025-7194Public exploitNetwork attack vector

Authenticated device crash via unbounded sprintf copy

Published Jul 8, 2025 · Updated Jul 8, 2025

Stack-based buffer overflow in D-Link DI-500WF 17.04.10A1T allows remote authenticated users to crash the device via HTTP requests. The ip_position.asp handler passes the GET ip parameter to sprintf, copying unbounded user input into a fixed-size stack buffer and overwriting stack memory. Administrative web-interface access is required; exploitation can crash the device or execute code with jhttpd privileges.
