OVERVIEW
NCCIC/ICS-CERT received a report from HPs Zero Day Initiative (ZDI) concerning
command injection vulnerabilities in Schneider Electrics ProClima software
package. These vulnerabilities were reported to ZDI by security researchers
Ariele Caltabiano, Andrea Micalizzi, and Brian Gorenc. Schneider Electric has
produced an update version that mitigates these vulnerabilities.
These vulnerabilities could be exploited remotely.
AFFECTED PRODUCTS
The following ProClima versions are affected:
ProClima Version 6.0.1 and previous.
IMPACT
Successfully exploiting these vulnerabilities could allow a remote attacker to
execute arbitrary code.
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
Schneider Electrics corporate headquarters is located in Paris, France, and
maintains offices in more than 100 countries worldwide.
The affected product, ProClima, is a configuration utility used to design
control panel enclosures to accommodate the thermal load from the
electrical/electronic devices inside and from the environment. According to
Schneider Electric, ProClima is used across several sectors including Critical
Manufacturing, Commercial Facilities, and Energy. Schneider Electric estimates
that these products are used primarily in the United States and Europe with a
small percentage in Asia.
VULNERABILITY CHARACTERIZATION
VULNERABILITY OVERVIEW
COMMAND INJECTION [a]
MDraw30.ocx control can be initialized and called by malicious scripts
potentially causing buffer overflows, which may allow an attacker to execute
code remotely.
CVE-2014-8513 [b], CVE-2014-8514 [c], and CVE-2014-9188 [d] have been assigned
to these vulnerabilities. A CVSS v2 base score of 10.0 has been assigned; the
CVSS vector string is (AV:N/AC:L/Au:N/C:C/I:C/A:C). [e]
COMMAND INJECTION [f]
Atx45.ocx control can be initialized and called by malicious scripts
potentially causing a buffer overflow, which may allow an attacker to execute
code remotely.
CVE-2014-8511 [g] and CVE-2014-8512 [h] have been assigned to these
vulnerabilities. A CVSS v2 base score of 10.0 has been assigned; the CVSS
vector string is (AV:N/AC:L/Au:N/C:C/I:C/A:C). [i]
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
Schneider Electric has released an updated version of the ProClima software,
Version 6.1.7, which mitigates these vulnerabilities. Customers are encouraged
to download the new version and update their installations. It is important
that customers first uninstall the current version. The new version can be
downloaded from Schneider Electrics web site at the following location:
http://www.schneider-electric.com/ww/en/download/document/ProClima_software
For further information on these vulnerabilities, please see Schneider
Electrics security notification (SEVD 2014-344-01) at Schneider Electrics
cybersecurity web page:
http://www2.schneider-electric.com/sites/corporate/en/support/cybersecurity/cyber-security-vulnerabilities-sorted.page
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 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.
