Vulnerability from csaf_abb - Published: 2025-01-20 00:30 - Updated: 2025-02-14 00:30
Summary
FLXeon Controllers Cyber Security Advisory

Notes

Summary
An update is available that resolves a privately reported vulnerability in the product versions listed as affected in this advisory. FLXEON devices are not intended to be internet-facing. A product advisory issued in June 2023 informed customers of this parameter. An attacker can successfully exploit these vulnerabilities and could take remote control of the product and potentially insert and run arbitrary code. ABB requires, as noted in previous security advisories and user documentation, that FLXEON should not be exposed to the internet or any other insecure network. Note: In order to exploit an FLXEON, an attacker would need a misconfigured system. ABB strongly advises customers and system integrators to follow the instructions documented in: FBXi, CBXi and ASPECT® SOLUTIONS, which can be downloaded from the ABB library (See in the reference section).
General security recommendations
For any installation of software-related ABB products and especially for products in scope of the FLXEON product line, we strongly recommend the following (non-exhaustive) list of cyber security practices: • Ensure that all FLXEON products are upgraded to the latest firmware version. Please find the latest version of FLXEON firmware on the respective product homepage • Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls and separate them from any general-purpose network (e.g. office or home networks). • Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks. • Never connect programming software or computers containing programming software to any network other than the network for the devices that it is intended for. • Scan all data imported into your environment before use to detect potential malware infections. • Minimize network exposure for all FLXEON ports and endpoints to ensure that they are not accessible directly from the Internet. • Ensure all nodes are always up to date in terms of installed software, operating system, and firmware patches as well as anti-virus and firewall. • When remote access is required, use secure methods, such as Virtual Private Networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available More information on recommended practices can be found in the following documents: FBXi, CBXi and ASPECT® SOLUTIONS ((HT0038)

In no event shall ABB or any of its suppliers be liable for direct, indirect, special, incidental or consequential damages of any nature or kind arising from the use of this document, or from the use of any hardware or software described in this document, even if ABB or its suppliers have been advised of the possibility of such damages. This document and parts hereof must not be reproduced or copied without written permission from ABB, and the contents hereof must not be imparted to a third party nor used for any unauthorized purpose.

Workarounds
Users accessing FLXEON remotely shall do this using a VPN Gateway allowing access to the particular network segment where FLXEON is installed and configured. Note: it is crucial that the VPN Gateway and Network is setup in accordance with best industry standards and maintained in terms of security patches for all related components.
Mitigating factors
The vulnerabilities reported in scope of this document are only exploitable if attackers can access the network segment where FLXEON is installed and exposed directly to the internet. ABB therefore recommends the following guidelines in order to protect customers networks: • FLXEON devices should never be exposed directly to the Internet either via a direct ISP connection nor via NAT port forwarding. If remote access to a FLXEON system is a customer requirement, the system shall operate behind a firewall. Users accessing FLXEON remotely shall do this using a VPN Gateway allowing access to the particular network segment where FLXEON is installed and configured. • Note: it is crucial that the VPN Gateway and Network is setup in accordance with best industry standards and maintained in terms of security patches for all related components. • ABB System Integrators shall change default passwords if they are still in use. • Ensure that all FLXEON products are upgraded to the latest firmware version. Please find the latest version of FLXEON firmware on the respective product homepage
