Validação inadequada de quantidade especificada em entrada

Ocorre quando a aplicação aceita um parâmetro que define uma quantidade (tamanho de buffer, número de iterações, limite de registros) sem validar se esse valor está dentro de limites seguros. Um atacante pode especificar quantidades excessivas, causando consumo de recursos, overflow de memória ou lógica comprometida.

Ejemplo

Um endpoint REST recebe `?limit=999999999` para pagination sem checar se o valor é razoável, causando alocação massiva de memória ou timeout. Ou um parser aceita `Content-Length: -1` sem validar valores negativos, causando comportamento indefinido.

Cómo mitigar

Sempre validar limites mínimos e máximos de qualquer quantidade recebida do usuário antes de usar em alocação de memória, loops ou operações de I/O. Defina ranges explícitos (ex: `1 ≤ limit ≤ 1000`) e rejeite valores fora desse intervalo.
