Frostbyte10 Bugs Put Thousands of Refrigerators At Major Grocery Chains At Risk

An anonymous reader quotes a report from The Register: Ten vulnerabilities in Copeland controllers, which are found in thousands of devices used by the world's largest supermarket chains and cold storage companies, could have allowed miscreants to manipulate temperatures and spoil food and medicine, leading to massive supply-chain disruptions. The flaws, collectively called Frostbyte10, affect Copeland E2 and E3 controllers, used to manage critical building and refrigeration systems, such as compressor groups, condensers, walk-in units, HVAC, and lighting systems. Three received critical-severity ratings. Operational technology security firm Armis found and reported the 10 bugs to Copeland, which has since issued firmware updates that fix the flaws in both the E3 and the E2 controllers. The E2s reached their official end-of-life in October, and affected customers are encouraged to move to the newer E3 platform. Upgrading to Copeland firmware version 2.31F01 mitigates all the security issues detailed here, and the vendor recommends patching promptly.

In addition to the Copeland updates, the US Cybersecurity and Infrastructure Security Agency (CISA) is also scheduled to release advisories today, urging any organization that uses vulnerable controllers to patch immediately. Prior to these publications, Copeland and Armis execs spoke exclusively to The Register about Frostbyte10, and allowed us to preview an Armis report about the security issues. 'When combined and exploited, these vulnerabilities can result in unauthenticated remote code execution with root privileges,' it noted.
To be clear: there is no indication that any of these vulnerabilities were found and exploited in the wild before Copeland issued fixes. However, the manufacturer's ubiquitous reach across retail and cold storage makes it a prime target for all manner of miscreants, from nation-state attackers looking to disrupt the food supply chain to ransomware gangs looking for victims who will quickly pay extortion demands to avoid operational downtime and food spoilage.
