CVE-2023-44018Public exploitNetwork attack vector

Remote code execution via unchecked domain length

Published Sep 27, 2023 · Updated Sep 24, 2024

Stack overflow in Tenda AC10U Firmware 15.03.06.49_multi_tde01 allows remote attackers to execute code or crash the router via HTTP. The add_white_node function passes the user-supplied domain parameter into a stack buffer without a length check, allowing an oversized value to overwrite memory. The exposed /goform/InsertWhite request requires network access but no authentication in the published proof of concept; exploitation can terminate httpd for denial of service and can enable root-level code execution.
