CVE-2024-57703Public exploitNetwork attack vector

Memory corruption via oversized Wi-Fi schedule value

Published Jan 16, 2025 · Updated Feb 4, 2025

Stack-based buffer overflow in Tenda AC8v4 16.03.34.06 allows remote attackers to corrupt memory via schedEndTime. The setSchedWifi handler accepts an oversized schedEndTime field at /goform/openSchedWifi and writes beyond a stack buffer; the exact copy instruction is undisclosed. NVD assesses unauthenticated network access, while CISA assesses adjacent access with low privileges, leaving the required access gate disputed.
