Many web developers are unaware of how SQL queries can be tampered with, and assume that an SQL query is a trusted command. It means that SQL queries are able to circumvent access controls, thereby bypassing standard authentication and authorization checks, and sometimes SQL queries even may allow access to host operating system level commands. OWASP uses the following definition for Injection Attacks: Injection flaws, such as SQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing unauthorized data.

[SQL Injection. Many web developers are unaware of how SQL queries can be tampered with, and assume that an SQL query is a trusted command. It means that SQL queries are able to circumvent access controls, thereby bypassing standard authentication and authorization checks, and sometimes SQL queries even may allow access to host operating system level commands.

SQL Injection Attacks are very common throughout the web. Hackers are known to use malicious SQL queries to retrieve data directly from the database. It basically exploits a security vulnerability. They are most common in online applications where the inputs are not correctly filtered. Consider the following login code. which is a valid SQL injection vector. (The original function, mysql_escape_string, did not take the current character set in account for escaping the string, nor accepted the connection argument. It is deprecated since PHP ) For example, consider one of the examples above. 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).

SQL injection is a technique (like other web attack mechanisms) to attack data driven applications. This attack can bypass a firewall and can affect a fully patched system.
