Frequently Asked Questions What causes the vulnerability? - The vulnerabilities are caused by: - Wrong configuration in T-MAC Plus IIS Server. - Wrong configuration of privileges of users. - Lack of encryption in communication protocol. What is T-MAC Plus? - T-MAC Plus is a Terminal Management System (TMS) that handles the different operations (receipt and dispatch product, access control, product movement in the tank farm, …) in a terminal. It is applicable to different type of products such as chemical and petroleum terminals, pipeline or refinery tankage, bulk plants or hydrogen terminals. The following components are affected: - TMAC Plus Web application - Communication protocol with Card Readers What might an attacker use the vulnerability to do? - An attacker who successfully exploited this vulnerability could cause the affected system node to stop or become inaccessible and allow the attacker to insert and run arbitrary code. How could an attacker exploit the vulnerability? - An attacker could try to exploit the vulnerability by creating a specially crafted message and sending the message to an affected system node. This would require that the attacker has access to the system network, by connecting to the network directly. Recommended practices help mitigate such attacks, see section Mitigating Factors. Could the vulnerability be exploited remotely? - No, to exploit this vulnerability an attacker would need to have physical access to an affected system node. Can functional safety be affected by an exploit of this vulnerability? - While these vulnerabilities primarily impact confidentiality, integrity, and availability, they do not directly affect functional safety in the traditional sense What does the update do? - The update removes the vulnerability by modifying the way that the T-MAC Plus web application and the communication protocol are configured. When this security advisory was issued, had this vulnerability been publicly disclosed? - No, ABB received information about this vulnerability through responsible disclosure. When this security advisory was issued, had ABB received any reports that this vulnerability was being exploited? - No, ABB had not received any information indicating that this vulnerability had been exploited when this security advisory was originally. Legal Notice and Terms of Use This product is provided subject to this Notification (https:\u002F\u002Fwww.cisa.gov\u002Fnotification) and this Privacy & Use policy (https:\u002F\u002Fwww.cisa.gov\u002Fprivacy-policy). 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\u002For 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.
