CVE-2024-9404: Denial-of-Service Vulnerability Identified in the VPort 07-3 Series

Published: December 4, 2024

This Alert Is From MOXA

As Industrial IoT (IIoT) adoption continues to proliferate, cybersecurity has become one of the top priorities. The Moxa Product Security Incident Response Team (PSIRT) takes a proactive approach to protect products from cybersecurity vulnerabilities. Moxa PSIRT investigates all reports of vulnerabilities that could potentially affect Moxa products. Moxa created a vulnerability management policy to provide guidance and information to our customers in the event of a reported vulnerability. The management policy ensures that Moxa’s customers have steady, unambiguous resources to help them understand how Moxa resolves or mitigates reported vulnerabilities. For any queries, please email [email protected].

Moxa’s IP Cameras are affected by a medium-severity vulnerability, CVE-2024-9404, which could lead to a denial-of-service condition or cause a service crash. This vulnerability allows attackers to exploit the Moxa service, commonly referred to as moxa_cmd, originally designed for deployment. Because of insufficient input validation, this service may be manipulated to trigger a denial-of-service.

This vulnerability poses a significant remote threat if the affected products are exposed to publicly accessible networks. Attackers could potentially disrupt operations by shutting down the affected systems. Due to the critical nature of this security risk, we strongly recommend taking immediate action to prevent potential exploitation.
