CVE-2023-45468Public exploitNetwork attack vector

Unauthenticated router crash via crafted pingWdogIp value

Published Oct 13, 2023 · Updated Sep 17, 2024

Buffer overflow in Netis N3 Firmware 1.0.1.865 and earlier allows remote attackers to crash the router through a crafted pingWdogIp value. Published materials identify an unchecked buffer copy involving pingWdogIp but do not name the affected function or destination buffer. No authentication or user interaction is required; successful exploitation makes the router unresponsive or crashes it, interrupting network service.
