CVE-2022-46589Public exploitNetwork attack vector

Unauthenticated memory corruption via netstat option overflow

Published Dec 30, 2022 · Updated Apr 11, 2025

Stack-based buffer overflow in TRENDnet TEW-755AP firmware 1.13B01 allows remote attackers to corrupt memory via a crafted netstat option. The tools_netstat function processes the cameo.cameo.netstat_option parameter without sufficient bounds enforcement and writes beyond its stack buffer. No authentication or user interaction is required; resulting memory corruption can crash the access point or permit code execution in the firmware context.
