OVERVIEW
Ivan Sanchez of WiseSecurity Team has identified a dll hijack vulnerability in
the ABB RobotStudio and Test Signal Viewer applications. ABB has produced new
versions that mitigate this vulnerability. Mr. Sanchez has tested the new
version to validate that it resolves the vulnerability.
AFFECTED PRODUCTS
The following ABB versions are affected:
RobotStudio Version 5.60 up to and including 5.61.01.01, and
Test Signal Viewer Version 1.5
IMPACT
The vulnerability could allow an attacker who successfully exploits it to
insert and run arbitrary code on an affected system.
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
ABB is a company based in Switzerland that maintains offices in several
countries around the world. ABB develops products in multiple critical sectors
that are deployed worldwide.
The RobotStudio software is a PC product used for offline programming and
simulation of ABB Robot system. The vulnerability exists in an executable file
included in the product versions listed above. The Test Signal Viewer software
is a PC product used for tuning motion parameters for external axes such as
track motion and turning tables. According to ABB, these products are deployed
across several industries including manufacturing, discrete automation, and
others. ABB estimates that these products are used globally.
VULNERABILITY CHARACTERIZATION
VULNERABILITY OVERVIEW
UNCONTROLLED SEARCH PATH ELEMENT[a]
The vulnerability can be exploited when an executable file is executed during
installation of RobotStudio to resolve the location of other DLLs to be
dynamically loaded by a third-party component. The executable file has
mistakenly been included, but not used in the distribution of all RobotStudio,
Versions 5.60 up to and including 5.61.01.01.
CVE-2014-5430[b] A CVSS v2 base score of 9.3 has been assigned; the CVSS vector
string is (AV:N/AC:M/Au:N/C:C/I:C/A:C).[c]
VULNERABILITY DETAILS
EXPLOITABILITY
This vulnerability is not exploitable remotely and cannot be exploited without
user interaction. The exploit is only triggered when a local user runs the
vulnerable application, which in certain scenarios can cause it to load a dll
file from an untrusted source.
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
The problem is corrected in the following product versions:
RobotStudio Version 5.61.02, and
Test Signal Viewer Version 1.6
These versions are available on the RobotWare 5.15.07.01 DVD and the RobotWare
5.61.02 DVD. The RobotWare 5.15.07.01 DVD and the RobotWare 5.61.02 DVD are
available for download at the following hyperlink:

ABB recommends that customers apply the update as early as convenient. ABB has
issued two Cyber Security Advisories providing further information. Please see
the ABB Cyber Security Alerts & Notifications web page at:
http://www.abb.com/cawp/abbzh254/2c9d1261d9fa1dcfc1257950002e4fbf.aspx
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
(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.
In addition, ICS-CERT recommends that users take the following measures to
protect themselves from social engineering attacks:
1. Do not click web links or open unsolicited attachments in email messages.
2. Refer to Recognizing and Avoiding Email Scams[d] for more information on
avoiding email scams.
3. Refer to Avoiding Social Engineering and Phishing Attacks[e] for more
information on social engineering attacks.
