Advisory (ICSA-14-189-02)
Innominate mGuard Unauthorized Leakage of System Data
Original release date: July 29, 2014
Legal Notice
All information products included in http://ics-cert.us-cert.gov are provided
"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 July 8, 2014, and is being released to the NCCIC/ICS-CERT web site.
The Applied Risk Research team has identified an unauthorized download of
system information from Innominate mGuard devices. Innominate has produced
a firmware patch that mitigates this vulnerability. This firmware patch
has been validated by the Applied Risk Research team, and the original
vulnerability research is referenced on at http://www.applied-risk.com
as ARA-2014001.
This vulnerability could be exploited remotely.
AFFECTED PRODUCTS
The following Innominate mGuard firmware versions are affected:
Innominate mGuard firmware Versions 4.0.0 up to Version 8.0.2
Innominate mGuard firmware Versions 7.6.4 patch release, and firmware
Versions 8.0.3, 8.1.0, 8.1.1, and higher are not affected.
IMPACT
Exploitation of this vulnerability could allow a remote unauthenticated
user access to release configuration information. While this is a minor
vulnerability, it represents a method for further network reconnaissance.
Impact to individual organizations depends on many factors that are unique
to each organization. ICS-CERT recommends that organizations evaluate
the impact of this vulnerability based on their operational environment,
architecture, and product implementation.
BACKGROUND
Innominate is a German-based company that sells products worldwide through
its international partners. Innominate was acquired by Phoenix Contact
in 2008.
The vulnerability affects only the mGuard products, which are industrial
security routers. They can be found in many critical infrastructure
sectors, including Communications, Critical Manufacturing, and Healthcare
and Public Health.
VULNERABILITY CHARACTERIZATION
VULNERABILITY OVERVIEW
INFORMATION DISCLOSURE[a]
An attacker using a carefully crafted URL may download a configuration
snapshot without prior authorization using the HTTPS CGI interface. The
configuration snapshot contains configuration data, current system
information and log files, but no confidential data such as RSA private keys,
Pre-Shared keys or passwords. An attacker might gather information about
network topology, traffic flows, and other connected systems from this data.
CVE-2014-2356[b] has been assigned to this vulnerability. A CVSS
v2 base score of 4.3 has been assigned; the CVSS vector string is
(AV:N/AC:M/Au:N/C:P/I:N/A:N).[c]
VULNERABILITY DETAILS
EXPLOITABILITY
This vulnerability could be exploited remotely.
EXISTENCE OF EXPLOIT
No known public exploits specifically target this vulnerability.
DIFFICULTY
An attacker with a moderate skill would be able to exploit this
vulnerability.
MITIGATION
All users of affected Innominate mGuard devices may either update to one
of the following firmware versions: 7.6.4, 8.0.3, 8.1.0, 8.1.1, or higher,
or use the hotfix-CVE-2014-2356.tar.gz patch-update to fix their systems
without updating any other component.
The patch can be applied by either uploading the patch-update as
"Local Update" or by the "Online Update" functionality and using
hotfix-CVE-2014-2356 as "Package set name." In addition, Innominate
recommends limiting access to the administrative interfaces via firewall
rules to the minimum necessary.
ICS-CERT encourages asset owners to take additional defensive measures to
protect against this and other cybersecurity risks.
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 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. ICS-CERT reminds organizations to perform proper impact analysis
and risk assessment prior to deploying defensive measures.
Additional mitigation guidance and recommended practices are
publicly available in the ICS-CERT 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
(www.ics-cert.org).
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.
