AWK-3131A Series Industrial AP/Bridge/Client Vulnerabilities

Published: June 25, 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].

Multiple product vulnerabilities were identified in Moxa’s AWK-3131A industrial AP/Bridge/Client Series. In response to this, Moxa has developed related solutions to address these vulnerabilities.
