Information Disclosure

AFFECTED PRODUCTS

The following U.motion Builder Software versions are affected:

U.motion Builder Versions 1.2.1 and prior.

IMPACT

A successful exploit of these vulnerabilities could allow an attacker to 
execute arbitrary commands or compromise the confidentiality, integrity, and 
availability of the system.

MITIGATION

Schneider Electric says a firmware update, which includes fixes for these 
vulnerabilities, is scheduled for availability to download by the end of 
August. When available, it is highly recommended that U.motion Builder users 
apply the patch in a timely manner.

Schneider Electrics security notice SEVD-2017-178-01 is available at the 
following location:

http://www.schneider-electric.com/en/download/document/SEVD-2017-178-01/ (link

NCCIC/ICS-CERT recommends that users take defensive measures to minimize the 
risk of exploitation of these vulnerabilities. Specifically, 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. 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.

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.

VULNERABILITY OVERVIEW
