Falhas do tipo CWE-400

Consumo não controlado de recursos

A aplicação não limita adequadamente o consumo de recursos (memória, CPU, conexões, disco) em resposta a requisições ou eventos, permitindo que um atacante esgote os recursos disponíveis. Resultado: negação de serviço, travamento ou crash da aplicação.

Exemplo

Um servidor web que aceita uploads sem limite de tamanho permite que um atacante envie um arquivo gigante, preenchendo o disco e derrubando o serviço. Outro cenário: aceitar conexões TCP indefinidamente sem timeout, até esgotar o número máximo de sockets do sistema operacional.

Como mitigar

Implemente limites explícitos: tamanho máximo de requisição/arquivo, timeout de conexão, limite de memória por processo, rate limiting. Use filas com capacidade máxima e rejeite requisições excedentes com mensagem de erro clara (HTTP 429, por exemplo).
