CVE-2026-94953Network attack vector

Stack corruption via unchecked repeater WEP key

Published Sep 29, 2026 · Updated Sep 29, 2026

A stack-based buffer overflow in TOTOLINK N150RT firmware 3.4.0-B20201030 allows attackers to corrupt stack memory via its web interface. The /boafrm/formAjaxSet handler processes ApCliWEPKey in the setting/setWiFiRepeaterConfig branch without keeping the value within a stack buffer. TOTOLINK documents login for web management, but authentication enforcement on this route and outcomes beyond memory corruption have not been established.
