Identifying the target: For fuzzing an application, we have to identify the target application. For instance, a FTP server with a specific IP and running on port 21.

Identifying inputs: As we know, the vulnerability exists because the target application accepts a malformed input and processes it without sanitizing. So, we have to identify those inputs that the application accepts. For instance, the user name and password are input in the FTP server.

Creating fuzz data: After getting all the input parameters, we have to create invalid input data to send to the target application. Fuzzing data is often known as payloads.

Fuzzing: After creating the fuzz data, we have to send it to the target application.

Monitoring the exceptions and logging: Now we have to watch the target application for interesting responses and crashes and save this data for manual analysis. Monitoring web application fuzzing is a bit different,...
