CVE-2026-2885Public exploitNetwork attack vector

Authenticated web-server crash via unchecked strcpy

Published Feb 21, 2026 · Updated Feb 21, 2026

Stack-based buffer overflow in D-Link DWR-M960 1.01.07 allows remote authenticated users to crash its web server via a crafted HTTP request. The sub_469104 handler in /boafrm/formIpv6Setup passes the request-controlled submit-url value to strcpy, copying it into the fixed-size wizard_htm buffer without a length check. A valid management session and save_apply parameter are required; the published proof of concept crashes the web server and leaves the device unreachable.
