CVE-2025-13305Public exploitNetwork attack vector

Code execution via unchecked traceroute host formatting

Published Nov 17, 2025 · Updated Nov 18, 2025

Stack buffer overflow in five D-Link router models running 1.01.07 allows remote attackers to execute arbitrary code. The traceroute handler's sub_421080 function passes the unbounded host parameter to sprintf when building a command in a 256-byte stack buffer. The public proof of concept states that authentication is not required and demonstrates a web-server crash; code execution requires control of overwritten stack data.
