CVE-2024-9567Public exploitNetwork attack vector

Authenticated router crash via oversized curTime input

Published Oct 7, 2024 · Updated Oct 7, 2024

Buffer overflow in D-Link DIR-619L B1 2.06 allows remote authenticated users to crash the router through a crafted HTTP request. Public materials identify curTime as attacker-controlled input to formAdvFirewall but do not disclose the exact copy call or destination buffer. Access to the web configuration interface is required; the demonstrated consequence is a router crash, while code execution has not been shown.
