An SQL injection is often used to attack the security of a website by inputting SQL statements in a web form to get a poorly designed website to perform operations on the database (often to dump the database content to the attacker) other than the usual operations as intended by the designer. SQL injection is a code injection technique that exploits a security vulnerability in a website's software. The vulnerability happens when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL commands are thus injected from the web form into the database of an application (like queries) to change the database content or dump the database information like credit card or passwords to the attacker. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database.
