CVE-2025-14704 is a path traversal vulnerability identified in the Shiguangwu sgwbox N3 device, version 2.0.25. The vulnerability resides in an unspecified function within the /eshell API component, which improperly sanitizes user-supplied input used in file path operations. This flaw enables remote attackers to craft malicious requests that traverse directories outside the intended scope, potentially accessing sensitive files or directories on the device's filesystem. The attack vector is network-based, requiring no authentication or user interaction, which significantly lowers the barrier for exploitation. The vulnerability has a CVSS 4.0 score of 6.9, reflecting medium severity, with the vector indicating low complexity and no privileges required. Although no official patch or vendor response has been issued, public exploit code is available, increasing the likelihood of exploitation in the wild. The impact includes unauthorized disclosure of sensitive information, potential modification of files, and disruption of device operations. The affected product, sgwbox N3, is typically used in industrial or specialized network environments, where device compromise could have operational consequences. The lack of vendor engagement and patch availability necessitates proactive defensive measures by users and administrators.

For European organizations, the exploitation of CVE-2025-14704 could lead to unauthorized access to sensitive configuration files, credentials, or operational data stored on the sgwbox N3 device. This could compromise confidentiality and integrity, potentially allowing attackers to pivot within internal networks or disrupt industrial processes. The availability impact is limited but possible if critical files are modified or deleted. Organizations relying on Shiguangwu devices in sectors such as manufacturing, energy, or telecommunications may face operational disruptions or data breaches. Given the remote exploitability without authentication, attackers could target exposed devices directly over the internet or through compromised internal networks. The public availability of exploit code increases the risk of opportunistic attacks. The vendor's lack of response and absence of patches heighten the urgency for organizations to implement compensating controls to mitigate potential damage.

Since no official patch is available, European organizations should implement immediate compensating controls. These include restricting network access to the sgwbox N3 devices by placing them behind firewalls or VPNs, limiting exposure to untrusted networks. Employ strict access control lists (ACLs) to allow only trusted management hosts to communicate with the /eshell API endpoint. Monitor network traffic for unusual or suspicious requests targeting the /eshell path, using intrusion detection or prevention systems (IDS/IPS) with custom signatures for path traversal patterns. Regularly audit device configurations and filesystem integrity to detect unauthorized changes. If feasible, isolate affected devices from critical network segments to reduce lateral movement risk. Engage with Shiguangwu or third-party security vendors for potential unofficial patches or workarounds. Maintain up-to-date backups of device configurations and data to enable recovery in case of compromise. Finally, educate operational technology (OT) and IT teams about this vulnerability and the importance of layered defenses.
