CWE-749 Detection Process Using Quark Script API
================================================

Let’s use the above APIs to show how the Quark script finds this vulnerability.

First, we design a detection rule ``configureJsExecution.json`` to spot on behavior using the method ``setJavascriptEnabled``. Then, we use the API ``methodInstance.getArguments()`` to check if it enables JavaScript execution on websites. Finally, we look for calls to the method ``addJavaScriptInterface`` in the caller method. If yes, the APK exposes dangerous methods or functions to websites. That causes CWE-749 vulnerability.
