This advisory is a follow-up to the alert titled ICS-ALERT-15-224-04 Moxa ioLogik E2210 VulnerabilitiesICS-ALERT-15-224-04 Moxa ioLogik E2210 Vulnerabilities, https://ics-cert.us-cert.gov/alerts/ICS-ALERT-15-224-04, web site last accessed March 03, 2016. 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.
Moxa reports that the vulnerabilities affect the following versions of ioLogik:
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.
The device transmits or stores authentication credentials that are not sufficiently encrypted.
CVE-2016-2282NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-2282, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. 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).CVSS Calculator, https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N, web site last accessed March 03, 2016.
The device stores or transmits sensitive data using an encryption scheme that is not strong enough for the level of protection required.
CVE-2016-2283NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-2283, NIST uses this advisory to create the CVE web site report. This web site will be active sometime after publication of this advisory. 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).CVSS Calculator, https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, web site last accessed March 03, 2016.
These vulnerabilities could be exploited remotely.
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:

http://www.moxa.com/support/sarch_result.aspx?type=soft&prod_id=15&type_id=5
Moxa also recommends that customers use a secured router or a VPN tunnel to protect internet communication.
ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available in the ICSβCERT Technical Information Paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site (http://ics-cert.us-cert.gov/).
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
