SQL injection is one of old & dangerous web application vulnerabilities. Attackers can execute malicious SQL command that allow attackers to control a web application database. It lets attackers access or delete data and change application database. SQL injection vulnerability could affect any website or web application and it occurs when an application uses untrusted data. When an application does not properly sanitize untrusted data before adding it to SQL query attackers can insert malicious SQL commands which database will execute. Attackers can use SQL injection vulnerability to bypass an application’s authentication and retrieve data of an entire database. Also, attackers can add, modify and delete data in database and it leads to affect data integrity. SQL injection can provide attackers with unauthorized access to sensitive data including personal information, business secrets and intellectual property. What attackers can do with SQL? SQL is designed for managing data stored in database server. With SQL injection vulnerability, attackers can bypass authentication and it could allow the complete disclosure of data residing on database server. Also attackers could use SQL injection to alter or delete data on database server, affecting data integrity. When data is deleted from database server, it affects an application’s availability until database is restored. AIONCLOUD protects your website from SQL injection.
