CVE-2025-6367Public exploitNetwork attack vector

Code execution via unchecked web-filter parameters

Published Jun 20, 2025 · Updated Jun 23, 2025

Stack-based buffer overflow in D-Link DIR-619L 2.06B01 allows remote authenticated users to crash the router through a crafted web request. The boa formSetDomainFilter handler copies oversized curTime, sched_name, or url form values into a local stack buffer without a length check, overwriting its return address. Access to the router's web-management interface is required; the demonstrated result is persistent service interruption, while return-address control enables arbitrary code execution.
