What type of injection involves inserting false information into a database?

The selection of SQL injection is appropriate because SQL injection specifically targets databases by submitting malicious SQL queries through user input fields. This method allows attackers to manipulate database queries by inserting or altering data, which can lead to unauthorized access, data leakage, or even complete control over the database.

SQL injection exploits vulnerabilities in applications that fail to properly validate or sanitize user input before integrating it into SQL statements. By inserting false information or crafted SQL commands, attackers can execute operations such as retrieving sensitive data, modifying records, or executing administrative commands on the database.

In contrast, the other types listed involve different vectors of attack. XML injection targets XML data structures, LDAP injection focuses on manipulating LDAP queries, and command injection involves executing arbitrary system commands. Each of these has unique characteristics and contexts, but none specifically center around inserting false information into a database in the same impactful way as SQL injection does.
