CVE-2024-28537Public exploitNetwork attack vector

Memory corruption via unchecked page parameter

Published Mar 18, 2024 · Updated Oct 28, 2024

Stack overflow in fromNatStaticSetting in Tenda AC18 firmware 15.03.05.05 allows remote attackers to corrupt memory via a POST request. The function passes the user-controlled page value to sprintf without bounds checking, copying it into a local stack buffer and allowing overwrite of its return address. The request requires no authentication or user interaction, and the published proof of concept demonstrates an oversized value and device-disruption risk rather than code execution.
