Injeção de SQL

Fraqueza onde entrada do usuário é concatenada diretamente em comandos SQL sem validação ou sanitização, permitindo que um atacante insira código SQL malicioso. O banco de dados executa comandos não intencionais, comprometendo confidencialidade, integridade e disponibilidade dos dados.

Exemplo

Um formulário de login concatena o usuário digitado direto na query: `SELECT * FROM users WHERE login = '` + input + `'`. Se o usuário digita `admin' OR '1'='1`, a query vira `SELECT * FROM users WHERE login = 'admin' OR '1'='1'`, retornando todos os usuários e burlando autenticação.

Como mitigar

Use prepared statements (consultas parametrizadas) com placeholders, nunca concatene entrada do usuário. Valide e restrinja entrada (whitelist), aplique princípio do menor privilégio na conta do BD e use WAF como camada adicional.
