Compliance Impact

The vulnerability allows an attacker to execute arbitrary OS commands with the privileges of the web server by injecting commands through the ping module's IP address field.

This can lead to unauthorized access, data disclosure, and potential system compromise, which may result in violations of data protection regulations such as GDPR and HIPAA that require safeguarding sensitive data and ensuring system integrity.

Therefore, exploitation of this vulnerability could negatively impact compliance with these common standards and regulations by exposing sensitive information and compromising system security.

Executive Summary

CVE-2025-67447 is an OS Command Injection vulnerability in the Neterbit NW-431F Router, specifically in the network diagnosis (ping) module. The vulnerability occurs because the application does not properly sanitize user input entered in the IP address field before passing it to the system's ping command.

An attacker can exploit this flaw by injecting arbitrary operating system commands through the IP address input. These commands are then executed with the privileges of the web server, potentially allowing the attacker to run any command on the affected device.

A proof of concept involves entering payloads such as "8.8.8.8; ls" or "8.8.8.8; cat /etc/passwd" into the IP address field of the ping module and submitting the form to execute and observe the output of the injected commands.

Impact Analysis

This vulnerability can have severe impacts because it allows an attacker to execute arbitrary commands on the router with web server privileges.

• An attacker could gain unauthorized access to sensitive information stored on the device.
• They could manipulate or disrupt network operations by executing malicious commands.
• The attacker might use the compromised router as a foothold to launch further attacks within the network.
• Because the vulnerability has a high CVSS score (9.8), it represents a critical security risk that could lead to full compromise of the device.

Detection Guidance

This vulnerability can be detected by testing the network diagnosis (ping) module of the Neterbit NW-431F Router. Specifically, you can attempt to inject OS commands through the IP address input field in the ping module.

For example, you can enter payloads such as "8.8.8.8; ls" or "8.8.8.8; cat /etc/passwd" into the IP address field and submit the form. If the output of the injected command is displayed, it confirms the presence of the OS command injection vulnerability.

Mitigation Strategies

Since a fixed version of the software is not yet available, immediate mitigation steps should focus on limiting exposure to the vulnerable ping module.

• Restrict access to the network diagnosis (ping) module by limiting access to trusted users or internal networks only.
• Disable or block the ping functionality in the router's web interface if possible.
• Monitor web server logs for suspicious input patterns in the IP address field that may indicate attempted command injection.
• Implement network-level controls such as firewall rules to restrict access to the router's management interface.
