CVE-2024-9909Public exploitNetwork attack vector

Router crash via oversized curTime parameter

Published Oct 13, 2024 · Updated Oct 15, 2024

Buffer overflow in D-Link DIR-619L B1 2.06 allows remote authenticated users to crash the router through a crafted HTTP request. The formSetMuti handler processes an oversized curTime value without a length bound, overflowing its destination buffer. Access to the web-management interface and valid administrator credentials are required, and successful exploitation interrupts routing service.
