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.


The following IntraVue software versions are affected:

IntraVue, all Windows versions prior to Version 2.3.0a14.


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.


Network Vision is a US-based company headquartered in Newburyport, 

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.




The vulnerability can be exploited by unauthenticated users to execute 
arbitrary operating system commands on an affected server system.

CVE-2015-0977[b] has been assigned to this vulnerability. A CVSS v2 base score 
of 10.0 has been assigned; the CVSS vector string is 



This vulnerability could be exploited remotely.


No known public exploits specifically target this vulnerability.


An attacker with a low skill would be able to exploit this vulnerability.


Network Vision has released a new version of the IntraVues software that 
mitigates the code injection vulnerability. It is recommended that the new 
version be applied as soon as possible. Users who have software support 
contracts with Network Vision can upgrade to the newest version at no cost.

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

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 

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.
