If in both the ways a text box with the message appears, you can try to break the website with more tricky JS Injection methods. The following code snippet shows how a Singleton is created. javascript:alert (‘Executed’) If the newly opened page includes a text box with the message ‘Executed’, then this type of injection attack is possible for the tested form. It's quite easy to implement this pattern. If we were to instantiate more than one of these types of objects, we'd run into problems like incorrect app behaviour, resource overuse, and other confusing results. Fill this carefully because it will determine the nature of your application. Examples include caches, OkHttpClient, HttpLoggingInterceptor, Retrofit, Gson, SharedPreferences, the repository class, etc. This will take you to the config window asking about the SDK version etc. In a typical Android app, there are many objects for which we only need one global instance, whether you are using it directly or simply passing it to another class. Anytime one of these phones rings, the same owner picks it up. A phone is typically owned by a single person, while a person can own many phones. Select Inject language or reference and choose the language you want to inject. Let's use the example of a cellphone and its owner. Place the caret inside the string literal, tag, or attribute, in which you want to inject a language and press Alt+Enter (or use the intention action icon ). This Singleton class may be responsible for instantiating itself, or you can delegate the object creation to a factory class. Anytime multiple classes or clients request for that class, they get the same instance of the class. Veracode, Open Source or Free, Android, ASP.NET, C, C, C++, Classic ASP, COBOL. The Singleton Pattern is a software design pattern that guarantees a class has one instance only and a global point of access to it is provided by that class. One feature I especially liked was the Language Injection they demonstrated with RegEx and XML. Works with 20 languages including C, C++, C, JavaScript, Python, and Java.
