CVE-2025-28395Public exploitNetwork attack vector

Authenticated service crash via unchecked sprintf copy

Published Apr 1, 2025 · Updated Apr 14, 2025

Buffer overflow in D-Link DI-8100 firmware 16.07.26A1 allows remote authenticated users to crash jhttpd via a crafted host_ip value. The ipsec_road_asp function passes the controllable value to sprintf, which copies it into the stack variable v16 without a length check. An authenticated management session and access to ipsec_road.asp are required; only a crash is demonstrated, while arbitrary code execution is reported but not demonstrated.
