CVE-2022-45781Public exploitNetwork attack vector

Authenticated code execution via unbounded device-name copy

Published Nov 14, 2023 · Updated Sep 3, 2024

Stack buffer overflow in Tenda AX1803 1.0.0.1_2994 and earlier allows remote authenticated users to execute arbitrary code over HTTP. In /bin/tdhttpd, set_name_with_mac uses sprintf with the unbounded devName value and the format %s;1 to fill a 256-byte stack array. A valid management-session cookie and network access to /goform/SetOnlineDevName are required; a crafted POST can overwrite control data and yield a root shell.
