Validação inadequada da quantidade de dados em entrada

A aplicação não valida corretamente a quantidade, tamanho ou volume de dados que recebe do usuário, permitindo que entradas maiores ou menores que o esperado passem pelo controle. Isso abre espaço para ataques de negação de serviço, estouro de buffer, consumo excessivo de recursos ou processamento de dados malformados.

Example

Um serviço web aceita um parâmetro 'quantidade' para retornar registros, mas não limita o valor máximo. Um atacante envia quantidade=999999999, forçando a aplicação a alocar gigabytes de memória ou executar query que consome toda a CPU, derrubando o serviço para usuários legítimos.

How to mitigate

Implemente validação explícita para toda entrada numérica ou de tamanho: defina limites mínimos e máximos aceitáveis, rejeite silenciosamente o que sair desses intervalos e registre tentativas suspeitas. Use whitelist de valores válidos quando possível.
