# Moxa ioLogik E2200 Series Weak Authentication Practices
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
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.
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. According to Moxa, ioLogik is deployed across several sectors, including Commercial Facilities and Energy. Moxa estimates that these products are used primarily in the United States, Europe, and Asia.
### VULNERABILITY CHARACTERIZATION
# VULNERABILITY OVERVIEW
INSUFFICIENTLY PROTECTED CREDENTIALS
The device transmits or stores authentication credentials that are not sufficiently encrypted.
CVE-2016-2282 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N).
INADEQUATE ENCRYPTION STRENGTH
The device stores or transmits sensitive data using an encryption scheme that is not strong enough for the level of protection required.
CVE-2016-2283 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
### VULNERABILITY DETAILS
These vulnerabilities could be exploited remotely.
# EXISTENCE OF EXPLOIT
Exploits that target these vulnerabilities are publicly available.
An attacker with a low skill would be able to exploit these vulnerabilities.
MOXA has created new firmware versions with improved password encryption between the ioAdmin utility and the ioLogik E2200 device to mitigate these vulnerabilities. Moxa recommends installing these network security enhancements, which can be downloaded at the following locations:
Moxa also recommends that customers use a secured router or a VPN tunnel to protect internet communication.
