ColdFusion 2018 Update broke ajax calls

We've just gone from ColdFusion 2018 Update 3 to Update 10, and in the process all of the application's ajax calls are returning a 500 error "Parameter validation error for the STRUCTKEYEXISTS function.The function takes 2 parameters." The returnformat on some functions is JSON, on others it's plain. I've searched the application and can't find any instance of StructKeyExists that doesn't have two parameters. I suspect the issue is security related, but this is beyond my level of expertise. Any suggestions?

    I think we just have to rule out the possibilities.


    Fixed!

     

    Your observation that it was switching to fusebox552/Application.cfc alerted me to the fact that the mapping was wrong, it should have been fusebox551/Application.cfc.

     

    Fixing that didn't resolve the problem though, at least not on its own. I couldn't find an instance of StructKeyExists that had anything but two arguments, not in that file and not anywhere in the application. I still don't understand what triggered that specific error message.

     

    Anyway, while confirming the value of this.name, I noticed this.secureJSON was set to false. I set it to true with no positive effect, then I removed it entirely and voila! Even the Ajax calls that didn't return serialized data worked again.

     

    (I also had to address some case issues in the javascript since some of the returned data was undefined.)

     

    Even though your feedback didn't directly solve the issue, it ended up guiding me to the root of the problem and I don't know how long it would have taken me to get there on my own. Thank you so much!

    There might be a security issue, as you say. But my guess is that you have somewhere in your application used structKeyExists with less than 2, or with more than 2, arguments. Check the application and exception logs. What do you find there?

    Thanks for responding. I've just searched the entire application again and found no instance of StructKeyExists with anything but two parameters.

     

    The coldfusion-out and application logs both report...

     

    "Error [ajp-nio-127.0.0.1-8018-exec-8] - Parameter validation error for the STRUCTKEYEXISTS function.The function takes 2 parameters. The specific sequence of files included or processed is: C:\inetpub\Websites\ctecourse-dev-scoe-net\model\Ajax\SectorPathwayCBEDS.cfc, line: 4."

     

    Line 4 of SectorPathwayCBEDS.cfc is the first and only <cfargument> line for the first <cffunction> in the component. The same line is reported whether the page throwing the error uses the first function or one later in the file.

     

    It may help to know that the application uses Fusebox 5.51. The application worked flawlessy in ColdFusion 11 for years. A couple weeks ago we moved it to a new ColdFusion 2018 server, running with update 3, and still the application worked as it should. It was only after applying update 10 last week that things went awry.

    We're then left with one remaining possibility: check the occurrence of structKeyExists in all the Application.cfm/Application.cfc files.
