	SQL Injection - OWASP
		An SQL injection attack consists of insertion or "injection" of an SQL query via the input data from the client to the application.
		SQL injection attacks are another instantiation of an injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands.
		Confidentiality: Since SQL databases generally hold sensitive data, loss of confidentiality is a frequent problem with SQL Injection vulnerabilities.

	Testing for SQL Injection - OWASP
		A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such shutdown the DBMS), recover the content of a given file present on the DBMS filesystem and in some cases issue commands to the operating system.
		The latter case is known as "Blind SQL Injection".
		Through such operation it is possible, in case of SQL Injection, to join a query, purposely forged from the tester, to the original query.

	SQL injection - Wikipedia, the free encyclopedia
		SQL injection is a security vulnerability that occurs in the database layer of an application.
		This form of SQL injection occurs when a user supplied field is not strongly typed or is not checked for type constraints.
		SQL injection is easy to work around in most programming languages that target web applications or offer functionality.

	SQL Injection and Oracle, Part One
		SQL injection techniques are an increasingly dangerous threat to the security of information stored upon Oracle Databases.
		SQL Injection is a way to attack the data in a database through a firewall protecting it.
		As stated in the introduction, it is possible to inject into any piece of SQL that is dynamically built at run time where the input data is not filtered or checked, so it is possible to demonstrate SQL injection using PL/SQL and the ubiquitous tool SQL*Plus.

	CIACTech06-001: Protecting Against SQL Injection Attacks
		SQL injection is a real threat that is being used to exploit company systems and data.
		An SQL injection vulnerability results when a user is able to change the SQL queries sent to the database in ways that were unexpected by the designer of the website.
		The simplest SQL injection attack results when the user can change the value of a record or user ID to change which record is viewed on the returning form.

	ScottGu's Blog : Tip/Trick: Guard Against SQL Injection Attacks
		SQL Injection attacks are really nasty security vulnerabilities, and something all web developers (regardless of platform, technology or data layer) need to make sure they understand and protect themselves against.
		SQL Injection Attacks are something you need to worry about regardless of the web programming technology you are using (all web frameworks need to worry about it).
		He only uses SQL injection and he pokes around until he's able to retrieve the login cookies for all the users from the database.

	Preventing SQL Injection Attacks (Site not responding. Last check: )
		SQL injection attacks take advantage of code that does not filter input that is being entered directly into a form.
		In the previous code block it executes the built SQL script directly, if count is greater than one, then you know the values entered in for the user name and password were the ones matching the database.
		One method of preventing SQL injection is to avoid the use of dynamically generated SQL in your code.

	Imperva Glossary \| SQL Injection
		SQL injection is a technique used to take advantage of non-validated input vulnerabilities to pass SQL commands through a Web application for execution by a backend database.
		An attacker may use SQL injection to retrieve data from other tables as well.
		For example, the occurrence of a certain SQL signature in a parameter value might not be enough to alert for SQL injection attack but the same signature in correlation with error responses or abnormal parameter size of even other signatures may indicate that this is an attempt at SQL injection attack.

	How To: Protect From SQL Injection in ASP.NET
		SQL injection can occur when an application uses input to construct dynamic SQL statements or when it uses stored procedures to connect to the database.
		A successful SQL injection attack enables a malicious user to execute commands in your application's database by using the privileges granted to your application's login.
		In situations where parameterized SQL cannot be used and you are forced to use dynamic SQL instead, you need to safeguard against input characters that have special meaning to SQL Server (such as the single quote character).

	What is SQL injection? - a definition from Whatis.com
		An SQL query is a request for some action to be performed on a database.
		However, automated SQL injection programs are now available, and as a result, both the likelihood and the potential damage of an exploit has increased enormously.
		According to security experts, the reason that SQL injection and many other exploits, such as cross-site scripting, are possible is that security is not sufficiently emphasized in development.

	SQL Injection Attacks by Example
		This was part of a larger security review, and though we'd not actually used SQL injection to penetrate a network before, we were pretty familiar with the general concepts.
		"SQL Injection" is subset of the an unverified/unsanitized user input vulnerability ("buffer overflows" are a different subset), and the idea is to convince the application to run SQL code that was not intended.
		Microsoft's SQL Server supports a stored procedure xp_cmdshell that permits what amounts to arbitrary command execution, and if this is permitted to the web user, complete compromise of the webserver is inevitable.

	SQL Injection
		Almost all SQL injection attacks are immediately reflected, that means a malicious parameter moves from the client to the server, will be put together to a SQL query, sent to the database server and the result will be returned to the client.
		A popular goal of SQL injection attacks is to bypass authorization.
		In any SQL fragment, especially in any condition string (:conditions => "…"), the connection.execute() or the find_by_sql() function, it is not advisable to use string appending (string1 + string2), or the conventional Ruby #{…} mechanism to substitute strings.

	LWN: SQL injection attacks
		Injection also requires a certain amount of imagination to visualize the kinds of queries that might be going on behind the input boxes of a web form.
		SQL injections are clearly a serious security problem, but one that can be thwarted relatively easily once one understands the problem and the ways to program around it.
		Whining that the database has too many features that might be useful for someone exploiting SQL injection vulnerabilities in an unrelated application is not so much swatting the fly as cursing the publisher for printing a newspaper that's too hard to swing while the thing is still buzzing around your head.

	SQL injection tools for automated testing
		SQL injection is a security exploit in which the attacker adds SQL code to a Web form input box to gain access.
		Manual testing for SQL injection -- as described in this tip on sites that are vulnerable to SQL injection attacks and this paper on advanced SQL injection in SQL Server applications -- used to be the only way to determine if your database was vulnerable.
		Finding potential SQL injection holes is one thing but actually carrying out the attacks in an automated fashion is quite another.

	SQL Injection
		SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of SQL Server for parsing and execution.
		The primary form of SQL injection consists of direct insertion of code into user-input variables that are concatenated with SQL commands and executed.
		As long as injected SQL code is syntactically correct, tampering cannot be detected programmatically.

	Ask Tom: On Injecting and Comparing (Site not responding. Last check: )
		SQL injection occurs when an application program accepts arbitrary SQL from an untrusted source (think "end user"), blindly adds it to the application's SQL, and executes it.
		These unbound SQL statements are the ones that should be considered suspect: They are bad for your system's performance, but they may hold the keys to the kingdom as well.
		Executing SQL from the middle tier (logged in as some superuser) or when passed to a definer rights routine (because a stored procedure executes by default with the privileges of the definer of the routine) is especially dangerous.

	What is an SQL Injection Attack / Vulnerability?
		A SQL injection vulnerability can occur when a poorly-written program uses user-provided data in a database query without first validating the input.
		A simple example of SQL injection is a basic HTML form login in which you provide a username and password:
		The most common methods to prevent this kind of SQL injection vunerability are to check the user's input for dangerous characters like single-quotes; and using prepared statements, which tell the database exactly what to expect before any user-provided data is passed to it.

	SQL Injection and Oracle, Part Two
		The first installment offered an overview of SQL injection and looked at how Oracle database applications are vulnerable to this attack, and looked at some examples.
		On the surface, protection against SQL injection appears to be easy to implement but, in fact, it is not as easy as it looks.
		Again, SQL injection is a relatively simple technique and on the surface protecting against it should be fairly simple; however, auditing all of the source code and protecting dynamic input is not trivial, neither is reducing the permissions of all applications users in the database itself.

	[SQL Injection] Threat Classification - Web Application Security Consortium
		SQL Injection is an attack technique used to exploit web sites that construct SQL statements from user-supplied input.
		The first is vanilla SQL Injection in which the attacker can format his query to match the developer's by using the information contained in the error messages that are returned in the response.
		A common way to detect Blind SQL Injection is to put a false and true statement into the parameter value.
