CVE-2022-38325Public exploitNetwork attack vector

Authenticated code execution via unbounded sprintf

Published Sep 15, 2022 · Updated Aug 3, 2024

Buffer overflow in Tenda AC15 and AC18 firmware 15.03.05.19_multi allows remote authenticated users to execute arbitrary code. The httpd handler passes the filePath POST value directly to sprintf into a stack-local buffer, allowing it to overwrite the function return address. Access to the router's authenticated web interface is required; successful exploitation can take control of the device.
