ABB is aware of public reports of a vulnerabilities in product versions listed as affected in this advisory. An attacker who successfully exploited these vulnerabilities could cause the product to stop, make the product inacces-sible, take remote control of the product or insert and run arbitrary code. As part of ABB product lifecycle policy, once a product transitions to end-of-life, we discontinue maintenance, security patches, and technical support to focus on current and future technologies. While the product will continue to function, we strongly recommend implementing mitigations defined in this document, such as using a private APN cellular network between Arctic wireless gateways and ARM600 for establishing VPN tunnels, to mitigate security risks and avoid potential vulnerabilities. As part of ABB product lifecycle policy, once a product transitions to Limited state, we discontinue maintenance, security patches, and technical support to focus on current and future technologies.
