Detect JSON Insecure Deserialization Threats in JavaScript

JSON Insecure Deserialization (JID) is one of the many emerging cyber threats that you may encounter online. Previously, most websites were XML-based, but as more individuals and businesses are moving to JSON-based websites, this type of threat is becoming more prominent. The JID attacks focus on a security vulnerability that allows them to pass hostile serialized objects into a website or application and initiate unauthorized deserialization; this can result in the execution of malicious scripts, exposure of confidential information, and more. In this tutorial, we will show you how to detect JID threats from text input by using an API in JavaScript.

We will start by running this command to install jQuery:

bower install jquery

Next, we can call the function with the following code:

var settings = {
     "url": "https://api.cloudmersive.com/security/threat-detection/content/insecure-deserialization/json/detect/string",
     "method": "POST",
     "timeout": 0,
     "headers": {
          "Content-Type": "application/json",
          "Apikey": "YOUR-API-KEY-HERE"
     },
     "data": JSON.stringify("<string>"),
};
$.ajax(settings).done(function (response) {
     console.log(response);
});

This will inform you whether a JID attack was detected without any additional research or coding. Easy, right?
