CVE-2024-9404: Denial-of-Service Vulnerability Identified in Multiple PT Switches

Published: February 19, 2025

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].

Multiple PT switches are affected by a high-severity vulnerability, CVE-2024-9404, which could lead to a denial-of-service condition or cause a system or service crash. This vulnerability allows attackers to exploit the Moxa service, commonly referred to as moxa_cmd, originally designed for deployment purposes. Due to insufficient input validation, this service can be exploited to trigger a cold start or denial-of-service condition. 

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. Given the severity of this issue, immediate action is strongly recommended to mitigate potential exploitation.
