CVE-2022-44258Network attack vector

Authenticated memory corruption via unchecked traceroute command

Published Nov 23, 2022 · Updated Apr 25, 2025

A buffer overflow in setTracerouteCfg in TOTOLINK LR350 9.3.5u.6369_B20220309 allows remote authenticated users to corrupt memory. setTracerouteCfg writes data derived from the command parameter beyond a buffer boundary; the published material does not identify the destination buffer or copy routine. Access to the authenticated management interface is required, and the documented consequence is limited to memory corruption because no specific execution or service-failure outcome is established.
