Validação inadequada de entrada

O software recebe dados do usuário ou de fontes externas, mas não verifica ou verifica de forma incompleta se esses dados têm as propriedades necessárias para processar com segurança. Isso permite que entradas malformadas, maliciosas ou inesperadas passem por controles e causem comportamentos indevidos — desde crashes até injeção de código.

Example

Uma aplicação web recebe um parâmetro numérico via GET, mas não valida se é realmente um número inteiro válido antes de usá-lo em uma consulta SQL. Um atacante envia um valor com caracteres especiais (ex: `1' OR '1'='1`), conseguindo injetar código SQL direto no banco de dados.

How to mitigate

Implemente validação rigorosa na entrada: defina o tipo, formato, comprimento e intervalo esperados; rejeite tudo que não se encaixe. Use listas de caracteres permitidos ('whitelist'), escape de dados para o contexto específico (SQL, HTML, URL) e bibliotecas de validação consolidadas. Nunca confie em dados do cliente.
