An issue was discovered on Moxa MGate MB3170 and MB3270 devices before 4.1, MB3280 and MB3480 devices before 3.1, MB3660 devices before 2.3, and MB3180 devices before 2.1. Insufficient password requirements for the MGate web application may allow an attacker to gain access by brute-forcing account passwords.

An issue was discovered on Moxa MGate MB3170 and MB3270 devices before 4.1, MB3280 and MB3480 devices before 3.1, MB3660 devices before 2.3, and MB3180 devices before 2.1. An attacker can access sensitive information (e.g., conduct username disclosure attacks) on the built-in WEB-service without authorization.

Moxa IKS-G6824A series Versions 4.5 and prior, EDS-405A series Version 3.8 and prior, EDS-408A series Version 3.8 and prior, and EDS-510A series Version 3.8 and prior use plaintext transmission of sensitive data, which may allow an attacker to capture sensitive data such as an administrative password.

Moxa IKS and EDS store plaintext passwords, which may allow sensitive information to be read by someone with access to the device.

Moxa IKS and EDS do not implement sufficient measures to prevent multiple failed authentication attempts, which may allow an attacker to discover passwords via brute force attack.

Moxa MXView 2.8 allows remote attackers to read web server's private key file, no access control.

In Moxa ioLogik 2500 series firmware, Version 3.0 or lower, and IOxpress configuration utility, Version 2.3.0 or lower, sensitive information is transmitted over some web applications in clear text.

In Moxa EDS-G516E Series firmware, Version 5.2 or lower, the affected products use a weak cryptographic algorithm, which may allow confidential information to be disclosed.
