CinchOps Critical Alert for Houston Businesses: High-Severity Vulnerabilities in Moxa Industrial Network Devices
Recent discoveries have revealed critical security flaws in essential industrial network infrastructure components, highlighting the ongoing challenges in securing industrial control systems. This alert details two severe vulnerabilities that require immediate attention from organizations using Moxa networking equipment.
The Vulnerabilities
The identification of these vulnerabilities underscores the complexity of securing industrial network devices that often bridge critical infrastructure systems. These high-severity flaws could potentially allow malicious actors to compromise industrial networks, making immediate remediation crucial.
CVE-2024-9138 (CVSS Score: 8.6)
Type: Privilege Escalation via Hard-coded Credentials
Impact: Allows authenticated users to gain root-level system access
Risk: System compromise, unauthorized modifications, data exposure, service disruption
CVE-2024-9140 (CVSS Score: 9.3)
Type: OS Command Injection
Impact: Enables remote attackers to execute arbitrary code without authentication
Risk: Complete system compromise through improper input validation
Note: This vulnerability is particularly concerning as it can be exploited remotely by unauthenticated users
Affected Products
Understanding which devices are impacted is crucial for organizations to assess their exposure and prioritize remediation efforts. The vulnerabilities affect a wide range of Moxa’s industrial networking products, particularly those used in critical infrastructure and industrial automation environments.
The following Moxa devices are impacted by both vulnerabilities:
EDR-8010 Series (firmware ≤ 3.13.1)
EDR-G9004 Series (firmware ≤ 3.13.1)
EDR-G9010 Series (firmware ≤ 3.13.1)
EDF-G1002-BP Series (firmware ≤ 3.13.1)
NAT-102 Series (firmware ≤ 1.0.5)
OnCell G4302-LTE4 Series (firmware ≤ 3.13)
TN-4900 Series (firmware ≤ 3.13)
Additional products affected by CVE-2024-9138 only:
EDR-810 Series (firmware ≤ 5.12.37)
EDR-G902 Series (firmware ≤ 5.7.25)
Required Actions and Remediation
The remediation process for these vulnerabilities requires a systematic approach to ensure all affected devices are properly updated or protected. Organizations should prioritize these actions based on their risk exposure and the criticality of affected systems.
Immediate Actions Required:
Firmware Updates (Available Now)
Upgrade to firmware version 3.14 or later for:
EDR-8010 Series
EDR-G9004 Series
