Fallos del tipo CWE-770
2215 resultadosAlocação sem limite de recursos
A aplicação aloca recursos (memória, conexões, arquivos, threads) em nome do usuário sem impor limites, permitindo que um atacante esgote os recursos do sistema. O risco é negação de serviço: a aplicação ou servidor inteiro pode travar quando os recursos acabam.
Ejemplo
Um servidor web aceita requisições sem limitar quantas conexões simultâneas um único usuário pode abrir, ou um upload sem verificar tamanho máximo. Um atacante abre milhões de conexões ou envia arquivos gigantes até a memória/disco encher.
Cómo mitigar
Implemente quotas e limites por usuário/origem (rate limiting, máximo de conexões simultâneas, tamanho máximo de upload). Monitore consumo de recursos e recuse requisições que violem os limites com erro 429 ou similar.
