CVE-2024-41461Public exploitNetwork attack vector

Memory corruption via unchecked list1 copy

Published Jul 24, 2024 · Updated Oct 25, 2024

Stack-based buffer overflow in Tenda FH1201 1.2.0.14 allows remote attackers to corrupt memory via a crafted list1 request parameter. The DhcpListClient handler copies list1 into stack storage without checking its length, and the published proof of concept submits 2,000 bytes. The HTTP endpoint is network-reachable without authentication; public evidence demonstrates the overwrite path but does not establish reliable code execution.
