CVE-2025-3785Network attack vector

Authenticated code execution via Hostname stack overflow

Published Apr 18, 2025 · Updated Apr 18, 2025

Stack-based buffer overflow in D-Link DWR-M961 1.1.36 allows remote authenticated users to execute code via a crafted Hostname. The Authorization Interface accepts an overlong Hostname in /boafrm/formStaticDHCP without enforcing the destination stack buffer's bounds. Access to the router's authenticated management interface is required, and successful exploitation executes arbitrary code or crashes the affected service.
