CVE-2025-14534Public exploitNetwork attack vector

Service interruption via unbounded NatBind copy

Published Dec 11, 2025 · Updated Dec 11, 2025

Buffer overflow in UTT 进取 512W 3.1.7.7-171114 allows remote attackers to interrupt service via a crafted NatBind value. The /goform/formNatStaticMap handler passes NatBind to strcpy without bounding the copy into its destination buffer. The published request includes Digest administrator credentials despite the CNA's unauthenticated CVSS vectors, so unauthenticated reachability remains unresolved; the demonstrated consequence is denial of service rather than code execution.
