Executive Summary

CVE-2025-14709 is a critical buffer overflow vulnerability in Shiguangwu sgwbox N3 version 2.0.25. It occurs in the WIRELESSCFGGET interface within the file /usr/sbin/http_eshell_server due to improper handling of the 'params' argument. Specifically, the input buffer is copied to an output buffer without verifying that the input size fits, leading to a classic buffer overflow (CWE-120). This flaw allows remote attackers to exploit the system without authentication, potentially compromising confidentiality, integrity, and availability. [1, 2]

Impact Analysis

This vulnerability can be exploited remotely without authentication, allowing attackers to cause a buffer overflow that may lead to system crashes or denial-of-service (DoS) conditions. It impacts the confidentiality, integrity, and availability of the affected system, potentially allowing attackers to disrupt services or gain unauthorized control. [1, 2]

Mitigation Strategies

No patches or mitigations are currently known for this vulnerability. The vendor did not respond to the disclosure. The suggested immediate step is to replace the affected product to avoid exploitation. Monitoring for any suspicious activity targeting the WIRELESSCFGGET interface and restricting network access to the affected service may help reduce risk temporarily. [1]
