[1] [2] SQL injection must exploit a security vulnerability in an application's software, for example, 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.
An SQL injection takes advantage of SQL syntax to inject malicious commands that can read or modify a database or compromise the meaning of the original query. [13] For example, consider a web page that has two text fields which allow users to enter a username and a password.
An example of this in an Integer Overflow attack would be that the integer-based input field is not checking size of the value of the incoming data to ensure that the target variable is capable of managing the incoming value. This is the vulnerability that the associated exploit will take advantage of in order to carry out the attack.
The attack specifically targeted Yahoo Voice, formerly known as Associated Content, which Yahoo had acquired in May 2010 for $100 million (£64.5 million). Using SQL injection techniques, the hackers were able to extract the data from Yahoo's servers and subsequently post the compromised information publicly online. [1] [2] [3] [4]

Double URI-encoding, also referred to as double percent-encoding, is a special type of double encoding in which data is URI-encoded twice in a row. [6] In other words, double-URI-encoded form of data X is URI-encode(URI-encode(X)). [7]
The Asprox botnet (discovered around 2008), also known by its aliases Badsrc and Aseljo, is a botnet mostly involved in phishing scams and performing SQL injections into websites to spread malware. [1] It is a highly infectious malware which spreads through an email or through a clone website.
Major DBMSs, including SQLite, [5] MySQL, [6] Oracle, [7] IBM Db2, [8] Microsoft SQL Server [9] and PostgreSQL [10] support prepared statements. Prepared statements are normally executed through a non-SQL binary protocol for efficiency and protection from SQL injection, but with some DBMSs such as MySQL prepared statements are also available using a SQL syntax for debugging purposes.
