Vulnerabilities in web applications

SQL Injection

SQL injection is a code injection technique that exploits a security vulnerability occurring in the database layer of an application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed.

SQL injection attacks are also known as SQL insertion attacks. In other words, the application is forced to run SQL code that was not intended. If the application is creating SQL strings without consideration, the application manipulated data beyond secrecy and requirement.
