OVERVIEW
Researcher Jrgen Bilberger from Daimler TSS GmbH has identified a code
injection vulnerability in Network Visions IntraVue software. Network Vision
has produced a new version that mitigates this vulnerability.
This vulnerability could be exploited remotely.
AFFECTED PRODUCTS
The following IntraVue software versions are affected:
IntraVue, all Windows versions prior to Version 2.3.0a14.
IMPACT
Successful exploitation of this vulnerability could allow an unauthenticated
user to execute arbitrary operating system commands that could impact the
confidentiality, integrity, and availability of an affected server.
Impact to individual organizations depends on many factors that are unique to
each organization. NCCIC/ICS-CERT recommends that organizations evaluate the
impact of this vulnerability based on their operational environment,
architecture, and product implementation.
BACKGROUND
Network Vision is a US-based company headquartered in Newburyport,
Massachusetts.
The affected product, IntraVue, is a software package for network
visualization. According to Network Vision, IntraVue is deployed across
several sectors including Critical Manufacturing, Transportation Systems, and
Water and Wastewater Systems. Network Vision estimates that these products are
used globally with a significant portion in North America and Europe.

Additional mitigations could be implemented as interim prevention measures
until the new version is applied. The following mitigations could be used to
help limit the impact of the code injection vulnerability; however, the
following suggestions may not be appropriate for all environments. ICS-CERT
reminds organizations to perform proper impact analysis and risk assessment
prior to deploying defensive measures.
Isolate the vulnerable system from the Internet and untrusted systems;
however, if connectivity is required, use a VPN solution and implement network
monitoring.
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 a VPN is
only as secure as the connected devices.
Implement a runtime policy to prevent the use of any command that does not
appear in a whitelist of allowable commands.
Utilize good design practices that include network segmentation; use of DMZs
with properly configured firewalls to selectively control traffic; and monitor
traffic passed between zones and systems.
If possible, create isolated accounts using lowest privileges to accomplish
minimum required tasks.
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 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
(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.
