Unauthenticated router crash via unchecked page parameter

Published Dec 8, 2022 · Updated Apr 23, 2025

Stack overflow in Tenda W30E firmware 1.0.1.25(633) allows remote attackers to crash the router via a crafted page parameter. The /goform/P2pListFilter handler splices the page value into a stack buffer with sprintf without a size check, overwriting stack memory. The network request requires no privileges or user interaction according to the published assessment; demonstrated impact is service interruption, while confidentiality and integrity impact are not reported.
