Falhas do tipo CWE-1287

171 resultados

Validação insuficiente de tipo de entrada

A aplicação aceita entrada do usuário sem verificar se ela corresponde ao tipo de dado esperado (inteiro, string, booleano, etc.). Isso permite que um atacante envie dados de tipo inesperado, causando comportamento anômalo, bypass de lógica ou até execução de código malicioso.

Exemplo

Um formulário espera um ID numérico, mas não valida o tipo antes de usar: quando um atacante envia uma string com comando SQL ou script JavaScript em vez de um número, o código processa normalmente e a injeção acontece.

Como mitigar

Valide explicitamente o tipo de cada entrada (use type hints, schemas de validação como JSON Schema, ou funções de cast com tratamento de erro). Nunca confie no tipo declarado pelo cliente; revalide no servidor. Use casting seguro com falha clara se o tipo não corresponder.
