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).
Oracle implemented a special variable type for APEX called Substitution Variables (with a syntax of "&NAME."); however, these are insecure and can lead to SQL injections. When an injection occurs within a PL/SQL block, an attacker can inject an arbitrary number of queries or statements to execute.
In computing and telecommunications, the payload is the part of transmitted data that is the actual intended message. Headers and metadata are sent only to enable payload delivery [1] [2] and are considered overhead.
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.
sqlmap is a software utility for automated discovering of SQL injection vulnerabilities in web applications. [2] [3] <script></script> Usage.
Injection exploits are computer exploits that use some input or data entry feature to introduce some kind of data or code that subverts the intended operation of the system. Usually these exploits exploit vulnerabilities resulting from insufficient data validation on input and so forth.
An exploit is a method or piece of code that takes advantage of vulnerabilities in software, applications, networks, operating systems, or hardware, typically for malicious purposes.
Pro*C (also known as Pro*C/C++) is an embedded SQL programming language used by Oracle Database DBMSes.Pro*C uses either C or C++ as its host language. During compilation, the embedded SQL statements are interpreted by a precompiler and replaced by C or C++ function calls to their respective SQL library.
