Advisory (ICSA-16-173-03)
Rockwell Automation FactoryTalk EnergyMetrix Vulnerabilities
Original release date: July 26, 2016

"as is" for informational purposes only. The Department of Homeland Security
(DHS) does not provide any warranties of any kind regarding any information

OVERVIEW
This advisory was originally posted to the US-CERT secure Portal library on
June 21, 2016, and is being released to the NCCIC/ICS-CERT web site.
Rockwell Automation has identified authentication vulnerabilities in the
FactoryTalk EnergyMetrix application. Rockwell Automation has produced a new
version to mitigate these vulnerabilities.
These vulnerabilities could be exploited remotely.
AFFECTED PRODUCTS
The following FactoryTalk EnergyMetrix versions are affected:
FactoryTalk EnergyMetrix, Version 2.10.00 and prior versions.
IMPACT
Successful exploitation of these vulnerabilities may give unauthenticated
access to the affected system.
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
Rockwell Automation, which is a US-based company, provides industrial
automation control and information products worldwide across a wide range of
industries.
The affected product, FactoryTalk EnergyMetrix, is a web-enabled management
software package that captures, analyzes, stores, and shares energy data.
According to Rockwell Automation, the product is deployed across several
sectors, including Chemical, Commercial Facilities, Critical Manufacturing,
Energy, Government Facilities, Water and Wastewater Systems, and others.
Rockwell Automation estimates that the product is used worldwide.
VULNERABILITY CHARACTERIZATION
VULNERABILITY OVERVIEW
INSUFFICIENT SESSION EXPIRATION [a]
User credentials are not immediately invalidated after an explicit logout
action is performed by the user, which may allow an attacker to use these
credentials until reset.
CVE-2016-4531 [b] has been assigned to this vulnerability. A CVSS v3 base score
of 7.3 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). [c]
SQL INJECTION [d]
An anonymous user may be able to escalate privileges resulting in privileged
access to the application and its data files but not to the underlying
computer system. The impact of this vulnerability is highly dependent on the
users environment and the level of privilege the web server service account
has with its associated database.
CVE-2016-4522 [e] has been assigned to this vulnerability. A CVSS v3 base score
of 7.3 has been assigned; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). [f]
VULNERABILITY DETAILS
EXPLOITABILITY
These vulnerabilities could be exploited remotely.
EXISTENCE OF EXPLOIT
No known public exploits specifically target these vulnerabilities.
DIFFICULTY
An attacker with a low skill would be able to exploit these vulnerabilities.
MITIGATION
Rockwell Automation has released Version 2.20.00 and Version 2.30.00, which
both address the identified vulnerabilities. Rockwell Automation recommends
that FactoryTalk EnergyMetrix users install Version 2.30.00 or the latest
version.
Rockwell Automations new versions, Version 2.20.00 and Version 2.30.00, are
available at the following URL, with a valid account:
http://compatibility.rockwellautomation.com/Pages/MultiProductDownload.aspx?famID=1&crumb=112
(link is external)
In addition to applying the latest software version, Rockwell Automation
recommends applying the following additional mitigations, when possible:
Ensure that the least-privilege user principle is followed, and user/service
account access to shared resources (such as a database) is only granted with
the minimum amount of rights that are needed.
Configure and enable HTTPS on your FactoryTalk EnergyMetrix server, which will
help protect the confidentiality and integrity of information exchanged
between the web browser and server.
Use trusted software, software patches, antivirus/antimalware programs and
interact only with trusted web sites and attachments.
Employ training and awareness programs to educate users on the warning signs
of a phishing or social engineering attack.

ICS-CERT recommends, as quality assurance, that users test the update in a
test development environment that reflects their production environment prior
to installation. In addition, users should:
Minimize network exposure for all control system devices and/or systems, and
ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be
updated to the most current version available. Also recognize that VPN is only
as secure as the connected devices.
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 ICSCERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted 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.
