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).
Regarding SQL injection, one can use parameterized queries, stored procedures, whitelist input validation, and other approaches to help mitigate the risk of an attack. [11] Using object-relational mapping can further help prevent users from directly manipulating SQL queries.
sqlmap is a software utility for automated discovering of SQL injection vulnerabilities in web applications. [2] [3] 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.
Improper input validation [1] or unchecked user input is a type of vulnerability in computer software that may be used for security exploits. [2] This vulnerability is caused when "[t]he product does not validate or incorrectly validates input that can affect the control flow or data flow of a program." [1] Examples include: Buffer overflow
The program that may only be exposed to the malicious input (like web server backend) must first care about this input (buffer overruns, SQL injection, etc.). Such attacks may never occur for the program that is only internally used by authorized users in a protected infrastructure.
Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities.Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities. [1]
Oracle is combating legacy problems, such as old source code written without addressing concerns of SQL injection and privilege escalation, resulting in many security vulnerabilities which have taken time to fix and also generated incomplete fixes.
