CVE-2025-0566Public exploitNetwork attack vector

Authenticated memory corruption via crafted device MAC

Published Jan 19, 2025 · Updated Jan 21, 2025

Stack-based buffer overflow in Tenda AC15 15.13.07.13 allows remote authenticated users to corrupt memory via a crafted mac parameter. The formSetDevNetName handler for /goform/SetDevNetName writes the mac request-body value beyond a stack buffer. A valid management session is required, and the public record does not establish whether exploitation yields code execution, data access, or only a crash.
