Summary
AC500 V3 Multiple vulnerabilities

Notes

Summary
An update is available that resolves a publicly reported vulnerability in the product versions listed as affected in the advisory. An attacker who successfully exploited these vulnerabilities could call shell functions (CVE-2023-6357), crash the PLC (CVE-2024-5000), crash the web server of the PLC (CVE-2024-8175), grant read access to files (CVE-2024-12429) or enable command execution (CVE-2024-12430). The vulnerabilities CVE-2023-6357, CVE-2024-12429 and CVE-2024-12430 require successful authentication.
General security recommendations
For any installation of software-related ABB products we strongly recommend the following (non-exhaustive) list of cyber security practices: – 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 applications and endpoints to ensure that they are not accessible from the Internet unless they are designed for such exposure and the intended use requires such. – 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. Also, understand that VPNs are only as secure as the connected devices

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.

Workarounds
Workarounds are specific measures that a user can take to help block an attack, for example, temporarily disabling the vulnerable feature may remove the exposure with well-known impact on functionality. ABB has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they can help block known attack vectors. When a workaround reduces functionality, this is identified below as “Impact of workaround”. To exploit the vulnerabilities CVE-2023-6357, CVE-2024-12429 and CVE-2024-12430, successful authentication is required. Therefore, the affected products shall only be used with activated user management and by setting strong passwords. Details regarding the device user management are available from the application note “AC500 User Management with V3”. ABB strongly recommends using the online user management. This not only prevents an attacker from downloading and execute malicious code, but also suppresses start, stop, debug, or other actions on a known working application that could potentially disrupt a machine or system.
