Moxa Fixes Critical RCE Flaw in OT Devices
Moxa Patches Critical Vulnerabilities in Cellular Routers: What You Need to Know
On January 3, 2024, Moxa, a leading industrial networking device manufacturer, announced the release of crucial patches for two significant vulnerabilities found in its cellular routers, secure routers, and network security appliances. These devices are widely used in critical infrastructure sectors, making the timely updates essential for safeguarding sensitive operations. The primary vulnerability, identified as CVE-2024-9140, poses a critical risk with a severity rating of 9.3, allowing potential remote code execution (RCE) that could jeopardize system security and communications.
The second vulnerability, CVE-2024-9138, carries a high severity rating of 8.6. This flaw involves hard-coded credentials that could enable an authenticated user to escalate privileges, granting root-level access to the system. With many of Moxa’s 517 customers operating in critical sectors, including major players like Siemens, KPMG, Verizon, and Microsoft, addressing these vulnerabilities is paramount.
Understanding the Risks of Moxa’s Vulnerabilities
- CVE-2024-9140: This critical vulnerability allows unauthenticated execution of operating system commands, significantly increasing the risk of exploitation.
- CVE-2024-9138: This high-severity flaw could let a remote threat actor exploit hard-coded credentials to gain unauthorized access.
Trey Ford, Chief Information Security Officer at Bugcrowd, emphasized the importance of Moxa’s proactive stance in disclosing these vulnerabilities. He noted that critical infrastructure sectors often operate with relatively weak security measures, relying heavily on network isolation (air gap protections) for safety. “I’m glad they’re openly publishing this advisory,” Ford remarked, highlighting the need for thorough testing and validation of all critical suppliers and technologies.
The Importance of Vigilance in Network Security
Mayuresh Dani, manager of security research at Qualys Threat Research Unit, elaborated on the potential impact of these vulnerabilities. “Affected Moxa devices are typically deployed in essential industries such as transportation, utilities, energy, and telecommunications,” Dani explained. “If compromised, these devices could grant unrestricted access to internal networks and sensitive data, leading to a complete communication breakdown.”
What Should Moxa Users Do?
To mitigate risks associated with these vulnerabilities, users of Moxa devices should take the following steps:
- Apply Patches Immediately: Ensure that the latest patches are applied to all affected devices.
- Monitor Network Activity: Keep a close watch on network traffic for any unusual activities that could indicate exploitation attempts.
- Review Security Protocols: Assess and strengthen existing security measures to guard against potential breaches.
