Moxa’s Response Regarding the IPsec ESP Vulnerability

Published: May 16, 2022

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].

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
Moxa is investigating to determine if any of our products are affected by this vulnerability. At the time of publication, none of Moxa’s products are affected. Moxa's Product Security Incident Response Team (PSIRT) will keep monitoring the situation and if there are any updates to the status of the vulnerability that affects Moxa's products, we will provide an update immediately.
