CVE-2025-14706 is a critical remote command injection vulnerability affecting Shiguangwu sgwbox N3 version 2.0.25. The vulnerability resides in an unspecified function within the /usr/sbin/http_eshell_server binary, part of the NETREBOOT Interface. This interface appears to provide remote management or reboot capabilities. Due to improper input validation or sanitization, an attacker can inject arbitrary shell commands remotely without authentication or user interaction. The vulnerability is exploitable over the network with low complexity and no privileges required, making it highly accessible to attackers. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H) reflects that exploitation leads to full compromise of confidentiality, integrity, and availability of the affected device. The vendor was contacted early but did not respond or provide a patch, and no official remediation is currently available. A public exploit is known, increasing the likelihood of exploitation attempts. The affected product is likely used in network environments for device management or reboot functions, making this vulnerability a significant threat to operational continuity and security. Attackers exploiting this flaw could execute arbitrary commands, potentially gaining full control over the device, disrupting network operations, or using the device as a pivot point for further attacks.

For European organizations, the impact of this vulnerability is substantial. Shiguangwu sgwbox N3 devices, if deployed in network management, telecommunications, or critical infrastructure environments, could be fully compromised, leading to unauthorized access, data breaches, or denial of service. The ability to execute arbitrary commands remotely without authentication means attackers can disrupt services, manipulate configurations, or install persistent malware. This could affect availability of critical network services and compromise sensitive data. The lack of vendor response and patches increases the risk exposure. Organizations relying on these devices may face operational disruptions, financial losses, and reputational damage. Additionally, attackers could leverage compromised devices to launch lateral attacks within internal networks, escalating the overall security risk.

Given the absence of vendor patches, European organizations should implement immediate compensating controls. These include isolating affected devices within segmented network zones with strict firewall rules to restrict access to the NETREBOOT Interface. Employ network intrusion detection and prevention systems (IDS/IPS) to monitor and block suspicious command injection attempts targeting /usr/sbin/http_eshell_server. Disable or restrict remote management interfaces if not essential. Conduct thorough asset inventories to identify all sgwbox N3 devices and assess exposure. Apply strict access control lists (ACLs) limiting management access to trusted IP addresses only. Regularly monitor device logs for anomalous activity indicative of exploitation attempts. Consider deploying virtual patching via web application firewalls (WAFs) or network proxies to filter malicious payloads. Finally, maintain heightened vigilance for any updates from the vendor or third-party security advisories and prepare for prompt patch application once available.
