SQL INJECTION


SQL INJECTION refers to the insertion of SQL metacharacter in user input, such that the attacker's queries are executed by the back-end database.Typically, attackers first determine if a site is vulnerable to such an attack by sending in the single quote(')  character. The result from an SQL INJECTION attack on a vulnerable site may range from a detailed error message, which discloses the back-end technology being used, or allowing the attackers to access restricted areas of the site because he manipulated the query to an always-true Boolean value,or it may even allow the execution of operating system commands.  SQL INJECTION techniques differ depending on the type of database being used. For instance, SQL INJECTION on an Oracle database is done primarily even the UNION keyword and is much more difficult than on the MS SQL Server, Whare multiple quires can be executed by separating them with the semi-colon. In its default configuration, MS SQL server runs with local system privi8leges and has the 'xp_cmdsell' the extended procedure, which allows execution of operating system commands.  SQL INJECTION are indeed a most prevalent form of attack since every other website use database to store and retrieve data. Here attackers provide user input which becomes part of SQL query. Dynamically generated query, when executed on database server without properr check, could let attackers retrieve unauthorized information without proper authentication and authorization.
