SQL injection is one of the most common web attack mechanisms utilized by attackers to steal sensitive data from organizations. While SQL Injection can affect any data-driven application that uses a SQL database, it is most often used to attack web sites.SQL Injection is a code injection technique that hackers can use to insert malicious SQL statements into input fields for execution by the underlying SQL database.
This technique is made possible because of improper coding of vulnerable web applications.These flaws arise because entry fields made available for user input unexpectedly allow SQL statements to go through and query the database directly. Attackers are constantly probing the Internet at-large and campus web sites for SQL injection vulnerabilities. They use tools that automate the discovery of SQL injection flaws, and attempt to exploit SQL injection primarily for financial gain (e.g.
PL/SQL Attacks. Understand SQL injection attacks against PL/SQL. PL/SQL, like stored procedures, can be vulnerable to SQL injection attacks.When PL/SQL code integrates user input into a query and executes it, we encounter exactly the same problem we have when we build a classic dynamic query.
Stealing personally identifiable information which is then used for identity theft).Because so many modern applications are data-driven and accessible via the web, SQL Injection vulnerabilities are widespread and easily exploited.
