1. EXECUTIVE SUMMARY
o CVSS v3 8.8
o ATTENTION: Low skill level to exploit
o Vendor: Rockwell Automation
o Equipment: FactoryTalk View SE
o Vulnerabilities: Cleartext Storage of Sensitive Information, Weak Encoding
for Password
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could lead to unauthorized
access to server data.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of FactoryTalk View SE are affected:
o FactoryTalk View SE Versions 9.0 and earlier
o FactoryTalk View SE Version 10.0
3.2 VULNERABILITY OVERVIEW
3.2.1 CLEARTEXT STORAGE OF SENSITIVE INFORMATION CWE-312
Due to usernames/passwords being stored in plaintext in Random Access Memory
(RAM), a local, authenticated attacker could gain access to certain
credentials, including Windows Logon credentials.
CVE-2020-14480 has been assigned to this vulnerability. A CVSS v3 base score of
8.8 has been assigned; the CVSS vector string is ( AV:L/AC:L/PR:L/UI:N/S:C/C:H/
I:H/A:H ).
3.2.2 WEAK ENCODING FOR PASSWORD CWE-261
The DeskLock tool provided with FactoryTalk View SE uses a weak encryption
algorithm that may allow a local, authenticated attacker to decipher user
credentials, including the Windows user or Windows DeskLock passwords. If the
compromised user has an administrative account, an attacker could gain full
access to the user's operating system and certain components of FactoryTalk
View SE.
CVE-2020-14481 has been assigned to this vulnerability. A CVSS v3 base score of
8.8 has been assigned; the CVSS vector string is ( AV:L/AC:L/PR:L/UI:N/S:C/C:H/
I:H/A:H ).
3.3 BACKGROUND
o CRITICAL INFRASTRUCTURE SECTORS: Chemical, Commercial Facilities, Critical
Manufacturing, Energy, Government Facilities, Water and Wastewater Systems
o COUNTRIES/AREAS DEPLOYED: Worldwide
o COMPANY HEADQUARTERS LOCATION: United States
3.4 RESEARCHER
Ilya Karpov and Evgeny Druzhinin, who are part of the independent research team
ScadaX Security, reported these vulnerabilities to Rockwell.
4. MITIGATIONS
Users of the affected versions of DeskLock provided with FactoryTalk View SE
are encouraged to update to an available software version that addresses the
associated risk, v10.0 or later. Users who are unable to update are directed
towards risk mitigation strategies provided below, and are encouraged, when
possible, to combine these with the general security guidelines to employ
multiple strategies simultaneously.
CISA 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.
CISA reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices
on the ICS webpage on us-cert.gov . 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 webpage on us-cert.gov 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 CISA for tracking
and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These
vulnerabilities are not exploitable remotely.
