Here’s a tangible proof point that some serious firmware vulnerabilities can now be found in hours, while deploying fixes to potentially impacted fielded devices can take months.
Following the refrigeration system attacks that disrupted hundreds of French supermarkets, Finite State conducted its own firmware analysis of the Danfoss controllers at the center of the security concerns, with some notable findings in “The Pain in the Cold Chain: How Weak Firmware Made Warm Freezers.”
Using an AI-driven analysis workflow, Finite State examined a pre-patch firmware build of the Danfoss AK-SM 800A refrigeration controller, without identifying the known CVEs in advance. Within hours, the workflow independently rediscovered two of the three previously disclosed vulnerabilities: an authentication bypass and a command-injection flaw that Finite State subsequently validated in its lab.
Jermaine Logan, Finite State’s Staff Product Security Engineer, authored Pain in the Cold Chain. And Finite State along with Jermaine are not claiming that these specific vulnerabilities were exploited in France, but its independent testing provides a revealing look at the underlying security weaknesses.
