CVE-2024-29671Public exploitNetwork attack vector

Unauthenticated code execution via unchecked hostname copy

Published Dec 16, 2024 · Updated Dec 17, 2024

Stack buffer overflow in NEXTU FLATA AX1500 Router 1.0.2 allows remote attackers to execute arbitrary code through a crafted POST request. The boa formStaticDHCP handler copies the hostname parameter with strcpy() without checking its length, overwriting the stack and return address. Network access to the router's HTTPS management service is sufficient; successful exploitation runs code as root and can interrupt service.
