ABB RobotStudio and Test Signal Viewer DLL Hijack Vulnerability

Original release date: November 04, 2014

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.


The following ABB versions are affected:

RobotStudio Version 5.60 up to and including, and

Test Signal Viewer Version 1.5


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.


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.




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

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]



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.


No known public exploits specifically target this vulnerability.


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


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 DVD and the RobotWare
5.61.02 DVD. The RobotWare 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:


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 

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.
