Published: January 5, 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].

PT-G503 Series firmware version v5.2 and prior are affected by multiple vulnerabilities in the old version of jQuery, weak cipher suites, and unsecure web cookies. Using the older jQuery version and weak cipher suites and not setting session cookie attributes properly caused these vulnerabilities. These vulnerabilities could put your security at risk in many ways, such as Cross-site Scripting (XSS) attacks, prototype pollution, data leaks, unauthorized access to user sessions, etc.
