2. RISK EVALUATION
An attacker could exploit the vulnerability by tricking a user to open a
specially crafted file, allowing the attacker to insert and run arbitrary code.
This vulnerability requires user interaction, and the exploit is only triggered
when a local user runs the affected product and loads the specially crafted
file.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of Panel Builder 800, an engineering tool for the
process panels included in the product suite Panel 800, are affected:
o Panel Builder 800, all versions.
3.2 VULNERABILITY OVERVIEW
3.2.1 IMPROPER INPUT VALIDATION CWE-20
An improper input validation vulnerability has been identified, which may allow
an attacker to insert and run arbitrary code on a computer where the affected
product is used.
CVE-2018-10616 has been assigned to this vulnerability. A CVSS v3 base score of
7.0 has been calculated; the CVSS vector string is (AV:L/AC:H/PR:N/UI:R/S:U/C:H
/I:H/A:H).

o COMPANY HEADQUARTERS LOCATION: Switzerland
3.4 RESEARCHER
Michael DePlante of Leahy Center and Michael Flanders of Trend Micro, both
working with Trend Micro's Zero Day Initiative, reported this vulnerability to
ABB. ABB reported it to NCCIC.
4. MITIGATIONS
ABB is currently investigating this vulnerability and recommends users follow
these suggestions until a corrected version is available.
Recommended security practices and firewall configurations can help protect a
process control network from attacks that originate from outside the network.
Such practices include:
o Conduct or reinforce cybersecurity awareness training for users of Panel
Builder 800:
- Describing general cybersecurity best practice recommendations for
industrial control systems,
- Informing that it is possible to infect Panel Builder files with
malware,
- Describing the importance of being careful with files that are received
unexpectedly and/or from unexpected sources.
o Carefully inspecting any files transferred between computers, including
scanning them with up-to-date antivirus software, so that only the
legitimate files are being transferred.
o User account management, appropriate authentication and permission
management using the principle of least privilege.
Please see the following cybersecurity advisory on the ABB website for more
information:

Launch
NCCIC recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet.
o Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
o 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.
NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
NCCIC 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
on the ICS-CERT website in the Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies.
Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to NCCIC for tracking
and correlation against other incidents.
No known public exploits specifically target this vulnerability. This
vulnerability is not exploitable remotely. High skill level is needed to
exploit.
