Remote service interruption via page parameter overflow

Published Apr 17, 2024 · Updated Aug 2, 2024

Stack-based buffer overflow in Tenda W30E firmware 1.0.1.25(633) allows remote attackers to interrupt service via a crafted request. The fromNatlimit HTTP request handler accepts an unbounded page parameter, causing data to exceed a fixed-size stack buffer. No privileges or user interaction are required, and the published impact is limited to availability rather than data disclosure or modification.
