Moxa’s Response Regarding the dnsmasq Vulnerability

Published: January 6, 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].

Moxa has studied a report by JSOF research labs that disclosed a set of vulnerabilities (known as ‘DNSpooq’) in dnsmasq. There are two types of DNSpooq vulnerabilities: buffer overflow and DNS response validation issues. Buffer overflow (CVE-2020-25681, CVE-2020-25682, CVE-2020-25683 and CVE-2020-25687) might lead to remote code execution and DoS attacks; and DNS response validation issues (CVE-2020-25684, CVE-2020-25685, and CVE-2020-25686) are vulnerable to DNS cache poisoning.

Moxa has investigated the vulnerabilities and has determined that the vulnerabilities affect AWK-3131A/4131A/1137C/1131A Series. In response to this, Moxa has developed related solutions to address these vulnerabilities.
