What type of attack does the term "injection" encompass?

The term "injection" primarily encompasses code injection attacks, which occur when an attacker is able to send malicious code as input to an application. This input can manipulate the application to execute unintended commands, often allowing unauthorized access or control over the system. Common forms of code injection include SQL injection, where attackers insert malicious SQL queries into an input field to access or manipulate database information; and command injection, where they execute arbitrary commands on the server.

These attacks exploit vulnerabilities in applications or web services that improperly validate or sanitize input, leading to severe security breaches. By using injection tactics, attackers can gain access to sensitive data, compromise user accounts, or alter application behavior, making it a significant threat in the field of cybersecurity. Understanding this form of attack is crucial for developing effective defenses and ensuring applications are designed with security in mind.
