injectionbased

Injectionbased is an adjective used to describe techniques, vulnerabilities, and attack vectors that rely on injecting data, code, or commands into a system to influence its behavior. The term is commonly used in cybersecurity and software engineering to categorize flaws where input is treated as executable code rather than as data.

Common forms include SQL injection, where untrusted input is concatenated into database queries; command injection, where input is executed by the host operating system; LDAP injection, where user data alters directory service queries; and various forms of web content injection, such as HTML or script injection. These vectors exploit insufficient input validation, improper encoding, or unsafe API usage.

Impact can range from data disclosure and modification to remote code execution and service disruption, depending on the target and the level of privileges. Many injection-based flaws arise from dynamic query construction, lack of parameterization, or error-prone string handling in code.

Mitigation involves secure coding practices: parameterized or prepared statements for database access, strict input validation and output encoding, least privilege database accounts, robust error handling, and guidance such as security testing and threat modeling. Frameworks and languages often provide built-in protections that reduce injection risk, but developers must use them correctly.
