3.4 RESEARCHER
Rockwell Automation reported these vulnerabilities to CISA.
4. MITIGATIONS
Rockwell Automation recommend users using the affected software to apply the
risk mitigations, if possible:
o Upgrade to CODESYS version 3.5.19.2 which has been released to mitigate
these issues.
o Additionally, we encourage the user to implement our suggested security
best practices to minimize risk of the vulnerability.
Users can use Stakeholder-Specific Vulnerability Categorization to generate
more environment-specific prioritization.
Additional information can be found in the CODESYS Advisory.
CISA recommends users take defensive measures to minimize the risk of
exploitation of this these vulnerabilities, such as:
o Minimize network exposure for all control system devices and/or systems,
ensuring they are not accessible from the internet .
o Locate control system networks and remote devices behind firewalls and
isolating them from business networks.
o When remote access is required, use more secure methods, such as Virtual
Private Networks (VPNs), recognizing VPNs may have vulnerabilities and
should be updated to the most current version available. Also recognize 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 cisa.gov/ics . Several CISA products detailing cyber
defense best practices are available for reading and download, including
Improving Industrial Control Systems Cybersecurity with Defense-in-Depth
Strategies .
CISA encourages organizations to implement recommended cybersecurity strategies
for proactive defense of ICS assets .
Additional mitigation guidance and recommended practices are publicly available
on the ICS webpage at cisa.gov/ics in the technical information paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies .
Organizations observing suspected malicious activity should follow established
internal procedures and report findings to CISA for tracking and correlation
against other incidents.
No known public exploitation specifically targeting this these vulnerabilities
has been reported to CISA at this time.
