Remediations
Vendor fixThe problem is corrected in the following product versions: B&R Automation Studio version 6.5 B&R recommends that customers apply the update at earliest convenience. The process to install updates is described in the user manual. The step to identify the installed product version is de-scribed in the user manual.
MitigationTo exploit this vulnerability, an attacker would need to intercept and redirect the communication between B&R Automation Studio and the target server, as well as present manipulated certificates that pass validation checks. B&R recommends operating B&R Automation Studio within Level 2 of the ABB ICS Cyber Security Reference Architecture when connecting to Level 1 devices via ANSL over TLS or OPC-UA. Operating in this trusted environment reduces the risk of successful exploitation drastically. Refer to section ?General security recommendations? for further advise on how to keep your system secure.

Frequently Asked Questions
What causes the vulnerability? - The vulnerability is caused by insufficient validation mechanisms for server certificates in the ANSL over TLS and OPC-UA client implementations. What is B&R Automation Studio? - B&R Automation Studio is an environment for developing and executing automation solutions, ranging from control and motion technology to HMI, operation, and integrated safety technology. What might an attacker use the vulnerability to do? - An attacker who successfully exploited this vulnerability could spoof a trusted server, potentially leading to the disclosure of confidential information or the alteration of data during transit. How could an attacker exploit the vulnerability? - An attacker could attempt to exploit this vulnerability by generating a maliciously crafted server certificate and manipulating network routing or name resolution to redirect traffic through a compromised node under their control. This would require that the attacker has access to the system network, by connecting to the network either directly or through a wrongly configured or penetrated firewall, or that he installs malicious software on a system node or other-wise infects the network with malicious software. Recommended practices help mitigate such attacks, see section Miti-gating Factors above. Could the vulnerability be exploited remotely? - Yes, an attacker who has network access to an affected system node could exploit this vulnerability. Recommended practices include that process control systems are physically protected, have no direct connections to the Internet, and are separated from other networks by means of a firewall system that has a minimal number of ports exposed. What does the update do? - The update removes the vulnerability by modifying the way that the ANSL and OPC-UA clients are validating server certificates. When this security advisory was issued, had this vulnerability been publicly disclosed? - No, B&R discovered this vulnerability as a part of its own security analysis. When this security advisory was issued, had B&R received any reports that this vulnerability was being exploited? - No, B&R had not received any information indicating that this vulnerability had been exploited when this security advisory was originally issued

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of these vulnerabilities.
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
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 recent version available. Also recognize VPN is only as secure as its 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. 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 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.

Recommended Practices
CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.
Minimize network exposure for all control system devices and/or systems, and ensure they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolate them from business networks.
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 recent version available. Also recognize VPN is only as secure as its 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. 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 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.
