an SQL Injection attack comes down to poor coding practices both within the front-end application and within the database stored procedures. Many developers have learned better development practices since ASP.NET was released, but SQL Injection is still a big problem between the number of legacy applications out there and newer applications built by devel-opers who didn't take SQL Injection. This is also called Error-based or Union based SQL Injection or first order Injection. The application is said to be vulnerable to In-band when the communication between the attacker and the application happens through a single channel. I.e. the attacker uses the same channel to enter the malicious string and to retrieve the data from the database. This is a straight forward technique. The.
