A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:
Method Injection, where dependencies are provided to a method only when required for specific functionality. Setter injection, where the client exposes a setter method which accepts the dependency. Interface injection, where the dependency's interface provides an injector method that will inject the dependency into any client passed to it.
The methods of injection can vary a great deal; in some cases, the attacker may not even need to directly interact with the web functionality itself to exploit such a hole. Any data received by the web application (via email, system logs, IM etc.) that can be controlled by an attacker could become an injection vector.
This injection will allow the attacker to overwrite the globalUrlConfig variable with a reference to the anchor element, which in turn overwrites the url variable and subsequently the scriptElem.src parameter, (due to the fact that url.href now refers to the href parameter of the anchor element) leading to arbitrary code execution.
In many systems, stored procedures can be granted access rights to the database that users who execute those procedures do not directly have. Some protection from SQL injection attacks Stored procedures can be used to protect against injection attacks. Stored procedure parameters will be treated as data even if an attacker inserts SQL commands.

On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...
