High-Severity Vulnerability in Moxa Network Devices
A critical security vulnerability, identified as CVE-2025-0676, has been discovered in several Moxa network devices, including secure routers and network security appliances. This vulnerability, with a CVSSv4 score of 8.6, poses a significant threat to network infrastructure by allowing attackers to execute arbitrary system commands and gain root-level access. The vulnerability is rooted in a command injection flaw within the tcpdump utility, which can be exploited by an authenticated attacker with console access. Successful exploitation could lead to privilege escalation, granting attackers persistent control over the device and potentially disrupting network services.
The affected Moxa products include the EDF-G1002-BP, EDR-810, EDR-8010, EDR-G9004, EDR-G9010, OnCell G4302-LTE4, and TN-4900 series, all with specific firmware versions. Moxa has acknowledged the issue and provided firmware updates to mitigate the risk. Organizations using these devices are strongly urged to update to the latest firmware versions or contact Moxa Technical Support for assistance.
This vulnerability highlights the ongoing risks associated with network device security and the importance of timely patch management. As attackers continue to exploit such vulnerabilities to gain unauthorized access and control, it is crucial for organizations to remain vigilant and proactive in securing their network infrastructure.
Threats and Vulnerabilities
CVE-2025-0676 is a high-severity command injection vulnerability affecting several Moxa network devices. It allows authenticated attackers with console access to execute arbitrary system commands due to improper input validation in the tcpdump utility. The potential impact includes privilege escalation to root-level access, enabling attackers to maintain persistent control over the device. This could disrupt network services and affect downstream systems relying on the compromised device's connectivity.
The vulnerability affects multiple Moxa product lines, including EDF-G1002-BP, EDR-810, EDR-8010, EDR-G9004, EDR-G9010, OnCell G4302-LTE4, and TN-4900 series with specific firmware versions. Known exploits could allow attackers to pivot within the network, posing a broader threat to organizational security.
Client Impact
Clients using affected Moxa devices may face operational disruptions if attackers exploit this vulnerability to gain control over network infrastructure. Such control could lead to data breaches or loss, financial consequences due to service downtime, and potential reputation damage. The risk of regulatory compliance issues also increases if sensitive data is compromised or if network availability is impacted.
From a compliance perspective, organizations must address this vulnerability promptly to avoid potential audits or penalties related to data protection regulations. Ensuring that network devices are updated with the latest security patches is essential for maintaining compliance and safeguarding against unauthorized access.
Mitigations
To mitigate the risks associated with CVE-2025-0676, clients should take the following actions:
- Upgrade affected Moxa devices to the latest firmware versions as specified by Moxa.
- Contact Moxa Technical Support for assistance with obtaining updated firmware for certain product lines.
- Implement strict access controls to limit console access to authorized personnel only.
- Regularly review and update network security policies to address emerging threats.
- Conduct routine security audits and vulnerability assessments on network devices.
By taking these steps, organizations can reduce the risk of exploitation and enhance their overall security posture. It is important to remain vigilant and proactive in applying security updates and monitoring network activity for signs of compromise.
