CVE-2024-30628Public exploitNetwork attack vector

Memory corruption via unchecked page parameter

Published Mar 29, 2024 · Updated Mar 14, 2025

Stack overflow in fromAddressNat in Tenda FH1205 2.0.0.7(775) allows remote attackers to corrupt memory via a crafted page value. The fromAddressNat handler processes the HTTP POST page parameter without enforcing the capacity of its destination stack buffer. No authentication or user interaction is required; oversized input can interrupt router service, while code execution is not demonstrated.
