Flaws In John Deere's Website Provides a Map To Customers, Equipment (securityledger.com) 31

Posted by BeauHD from the leaky-APIs dept.
chicksdaddy shares a report from The Security Ledger: Websites for customers of agricultural equipment maker John Deere contained vulnerabilities that could have allowed a remote attacker to harvest sensitive information on the company's customers including their names, physical addresses and information on the Deere equipment they own and operate, The Security Ledger reported. The researcher known as "Sick Codes" published two advisories on Thursday warning about the flaws in the myjohndeere.com website and the John Deere Operations Center website and mobile applications. In a conversation with Security Ledger, the researcher said that a he was able to use VINs (vehicle identification numbers) taken from a farm equipment auction site to identify the name and physical address of the owner. Furthermore, a flaw in the myjohndeere.com website could allow an unauthenticated user to carry out automated attacks against the site, possibly revealing all the user accounts for that site.

Sick Codes disclosed both flaws to John Deere and also to the U.S. Government's Cybersecurity and Infrastructure Security Agency (CISA), which monitors food and agriculture as a critical infrastructure sector. The information obtained from the John Deere websites, including customer names and addresses, could put the company afoul of data security laws like California's CCPA or the Personal Information Protection Act in Deere's home state of Illinois. However, the national security consequences of the company's leaky website could be far greater. Details on what model combines and other equipment is in use on what farm could be of very high value to an attacker, including nation-states interested in disrupting U.S. agricultural production at key junctures, such as during planting or harvest time.

The consolidated nature of U.S. farming means that an attacker with knowledge of specific, Internet connected machinery in use by a small number of large-scale farming operations in the midwestern United States could launch targeted attacks on that equipment that could disrupt the entire U.S. food supply chain, researchers warn. The Agriculture sector and firms that supply it, like Deere, lag other industries in cyber security preparedness and resilience. A 2019 report (PDF) released by Department of Homeland Security concluded that the "adoption of advanced precision agriculture technology and farm information management systems in the crop and livestock sectors is introducing new vulnerabilities" (and that) "potential threats to precision agriculture were often not fully understood or were not being treated seriously enough by the front-line agriculture producers."

        Umm no. Not even close to autonomous robots, sorry. They are still just big machines that pull heavy loads. They break down and need repairs that an average repairman can do if he had the codes to identify the problem. We do all our own maintenance and repairs ourselves whenever possible. Yes we're talking 500 hp heavy tractors. Having access to diagnostic codes to know what sensor has failed and the ability to reset codes in no way inhibits the safety of anyone.

            Have you seen the open source AgOpenGPS project? I think you'd find it quite interesting. In some ways it is primitive, and in other ways it's far more advanced than anything in my current tractors. In fact this year more than before I'm beyond frustrated with the primitive path planning of my Trimble NavII systems. As far as my John Deere machines go, oddly enough I find the old brown box monitor works way better than my newer 2630 when it comes to re-acquiring the line smoothly after a turn.

    • The term right-to-repair has become almost meaningless because it's too broad. To some it means the ability to read the vehicle CAN bus, and to others it means the unfettered ability modify the vehicle's firmware. These are two massively different things. No vehicle company is going to allow you to modify their firmware. For one, it's illegal because the first thing customers do is turn off emissions control. Second, it's dangerous because most vehicles now have some type of self driving, even if it's

    • Not true. I own a John Deere tractor and live on an old farm.

      There's plenty you can repair or customize on your deere tractor. As somebody else pointed out, some of their advanced machines are more like robots that plant and harvest for you. They're really cool, but it should come as no surprise that a computer controlled robot needs more sophisticated ways of maintaining than a tractor when you run a new hydraulic line or change the oil...

      I thought of half a dozen ways this information would be useful before finishing TFS. And that doesn't count the ones actually listed in TFS.

          Fair enough, and sorry for the unnecessary level of snark. But there's a far cry from, "I can't see how this would be useful" to 'Nobody's gaining anything with this "hack"'.

          The former may be true, but the latter is definitely not. For those of us who work in security, we have to be able to figure out how someone who is oriented toward destructive anarchy would exploit things like this.

          A lot of damage could be done by someone nefarious with this information.

    so basically "hacker" found a form that returns "account already registered" - and that is the whole basis of self promoting PR stunt?

      No.

      They also reported that the VIN alone will return a wealth of information about the owner. Including address and contact information.

      VINs can be harvested from auctions and sales sites. They can also be guessed or enumerated fairly easily.

      This is very, very stupid. The username disclosure vulnerability is fairly minor.
