CVE-2025-10034Public exploitNetwork attack vector

Authenticated memory corruption via unchecked ping6_ipaddr copy

Published Sep 6, 2025 · Updated Sep 8, 2025

Buffer overflow in D-Link DIR-825 1.08.01 httpd allows remote authenticated users to corrupt memory via a crafted IPv6 ping address. The get_ping6_app_stat function in ping6_response.cg copies the ping6_ipaddr argument without checking its length before writing to a bounded buffer. Access to the web-based management interface is required, and the published record does not establish command execution or persistent device compromise.
