CVE-2023-45577Network attack vector

Remote code execution via wanid stack overflow

Published Oct 16, 2023 · Updated Sep 18, 2024

Stack overflow in D-Link DI-7000G V2-series firmware allows remote attackers to execute arbitrary code through a crafted wanid value. Public records identify the H5/speedlimit.data handler and wanid parameter but do not disclose the exact unsafe memory-copy operation. Network access to the affected endpoint is sufficient; no authentication or user interaction is required, and code executes in the appliance context.
