Injeção de código

É quando uma aplicação incorpora dados não validados em um comando ou consulta que será interpretado como código. O atacante consegue injetar instruções maliciosas que são executadas com os privilégios da aplicação, como SQL, shell ou XML.

Example

Um formulário de login que monta uma query SQL concatenando diretamente a entrada do usuário: `SELECT * FROM usuarios WHERE email = '` + email_usuario + `'`. Um atacante digita `' OR '1'='1` e consegue bypassar a autenticação.

How to mitigate

Use prepared statements ou parameterized queries (bind variables), que separam dados de código. Valide e sanitize todas as entradas contra regras rígidas de whitelist, e aplique o princípio do menor privilégio nas contas de banco de dados e processos.
