CVE-2025-6565Public exploitNetwork attack vector

Memory corruption via unbounded Host header copy

Published Jun 24, 2025 · Updated Jun 25, 2025

Stack-based buffer overflow in NETGEAR WNCE3001 1.0.0.50 allows remote authenticated users to corrupt memory via an HTTP POST. In http_d, sscanf copies an attacker-controlled Host field into a 128-byte stack buffer without enforcing its capacity. Low-privileged access to the device's HTTP service is required; an oversized field can compromise confidentiality, integrity, and availability.
