### OVERVIEW

This advisory is a follow-up to the alert titled ICS-ALERT-15-224-04 Moxa ioLogik E2210 Vulnerabilitiesa that was published August 12, 2015, on the NCCIC/ICS-CERT web site.
Independent researcher Aditya Sood reported weak authentication vulnerabilities in Moxa ioLogik E2200 Ethernet Micro RTU controllers. Moxa has produced a network security enhancement to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely. Exploits that target these vulnerabilities are publicly available.



### AFFECTED PRODUCTS

Moxa reports that the vulnerabilities affect the following versions of ioLogik:

o ioLogik E2200 series, versions prior to 3.12, and
o ioAdmin Configuration Utility, versions prior to 3.18





### IMPACT

An attacker could exploit these vulnerabilities to gain access to the device to change settings and data on the target device.

Impact to individual organizations depends on many factors that are unique to each organization. ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.





### BACKGROUND

Moxa is a Taiwan-based company that maintains offices in several countries around the world, including the US, UK, India, Germany, France, China, Russia, and Brazil.

The affected product, ioLogik E2200 series, is a micro RTU controller for use in monitoring and control.
