CVE-2025-15232Public exploitNetwork attack vector

Authenticated code execution via unchecked parameter copy

Published Dec 30, 2025 · Updated Dec 30, 2025

Stack-based buffer overflow in Tenda M3 1.0.0.13(4903) allows remote authenticated users to execute code via a crafted POST request. The formSetAdPushInfo handler in /bin/httpd copies the mac or terminal parameter with memcpy() without bounds checking, corrupting its stack buffer. Low-privileged credentials and network access to /goform/setAdPushInfo are required; exploitation can hijack control flow or crash the controller.
