CVE-2024-9569Public exploitNetwork attack vector

Service crash via oversized curTime parameter

Published Oct 7, 2024 · Updated Oct 7, 2024

A buffer overflow in D-Link DIR-619L B1 2.06 allows remote authenticated users to crash the router web service via a crafted curTime value. The /goform/formEasySetPassword handler accepts curTime without a documented length bound before the overflow; no copy primitive is public. Access to the authenticated web configuration is required, and public evidence demonstrates service interruption rather than confirmed code execution.
