CVE-2025-14708Public exploitNetwork attack vector

Unauthenticated memory corruption via unchecked params copy

Published Dec 15, 2025 · Updated Dec 15, 2025

Buffer overflow in the WIREDCFGGET interface of Shiguangwu sgwbox N3 firmware 2.0.25 allows remote attackers to corrupt memory via params. The /usr/sbin/http_eshell_server handler copies attacker-controlled params data into an output buffer without verifying that the input fits. No authentication or user interaction is required; published evidence confirms memory corruption and service interruption, while code execution is not demonstrated.
