Authenticated OS Command Injection in Netis NX10 Firmware

Publication date: 2026-09-08

Last updated on: 2026-09-10

Assigner: VulnCheck

Description

Netis NX10 firmware V4.0.1.5808 and V3.0.0.4142 contain an OS command injection vulnerability in the ping diagnostic handler that allows authenticated administrators to execute arbitrary shell commands as root by injecting into the IpAddr parameter. The parameter is interpolated directly into a shell command executed through system() with an incomplete denylist that only blocks spaces, pipes, semicolons, and ampersands, leaving command substitution and alternate field separator expansion available for exploitation.

CWE

KEV

CWE ID	Description
CWE-78	The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Attack-Flow Graph

Executive Summary

This vulnerability is an OS command injection flaw in Netis NX10 firmware versions V4.0.1.5808 and V3.0.0.4142. It exists in the ping diagnostic handler and allows authenticated administrators to execute arbitrary shell commands as root by injecting into the IpAddr parameter. The parameter is directly interpolated into a shell command via system() with an incomplete denylist that only blocks spaces, pipes, semicolons, and ampersands, leaving other exploitation methods available.

Detection Guidance

Detecting this vulnerability requires checking for Netis NX10 devices running vulnerable firmware versions (V4.0.1.5808 or V3.0.0.4142). Use network scanning tools like Nmap to identify devices with open ports associated with Netis NX10. Inspect device firmware versions via the web interface or CLI if accessible. Test for command injection by attempting to inject payloads into the IpAddr parameter during ping tests.

Impact Analysis

An attacker with administrative access could exploit this to gain full root control over the device, potentially leading to complete compromise of the network infrastructure. This could allow unauthorized access, data theft, or disruption of services. The high CVSS scores (8.6 v4.0, 7.2 v3.1) indicate severe impact on confidentiality, integrity, and availability.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA due to unauthorized access to sensitive data or systems. GDPR requires protection against unauthorized processing, while HIPAA mandates safeguards for protected health information. A successful exploit could result in data breaches, triggering regulatory penalties and legal consequences.

Mitigation Strategies

Immediately update the Netis NX10 firmware to the latest non-vulnerable version if available. If no patch exists, restrict access to the device's administrative interface by blocking external connections and using a firewall. Disable unnecessary services like remote administration. Monitor network traffic for suspicious ping requests or command injection attempts.
