CVE-2026-6014Public exploitNetwork attack vector

Authenticated device compromise via webpage buffer overflow

Published Apr 10, 2026 · Updated Apr 10, 2026

Buffer overflow in D-Link DIR-513 1.10 allows remote authenticated users to corrupt memory through a crafted management POST request. The formAdvanceSetup handler processes the webpage argument at /goform/formAdvanceSetup without enforcing memory-buffer bounds. Low-privileged web-management access is required, and exploitation compromises device confidentiality, integrity, and availability.
