What is CVE-2020-6995?

Moxa's PT-7528 and PT-7828 series firmware versions contain a weakness in password requirements, potentially enabling unauthorized users to access the network. This vulnerability arises due to the implementation of weak password policies which fail to enforce strong credential standards. Such a flaw can lead to significant security risks, including unauthorized system manipulation. Organizations using these products should implement additional security controls or upgrade to secure versions without this weakness.
