Android WebView javascript



Android WebView vulnerability


WebView is an Android view that is used in order to display web content in anapplication. It uses the WebKit rendering engine in order to display web pagesand other content with the file:// and data:// protocols, which could be usedto load files and data content from the filesystem. WebView is used in variousAndroid applications as well, which display the web content in theapplication, such as applications offering signup and login, by framing theirmobile website in the application’s layout. We will be discussing more aboutWebKit and its rendering engine in the next chapter. For this chapter, we willonly be concerned about those applications that use WebKit.

Using WebView in the application


The use of WebView in an application is quite simple and straightforward.Let’s say we would like our entire activity to be a WebView component, loadingcontent from http://examplewebsite.com.Here is the code sample to implement WebView in an Android application: WebView webview = new WebView(this); setContentView(webview); webview.loadUrl(“http://vulnerable-website.com”); Another important thing that most developers end up doing in order to enhancethe functionality of the application, is enabling JavaScript (which is set toFalse by default) within the WebView implementation using the followingcommand: setJavascriptEnabled(true); The preceding command will ensure that JavaScript can be executed within theapplication and take advantage of the registered interfaces.
