Consumo descontrolado de recursos (Esgotamento de recursos)

A aplicação não limita ou valida adequadamente a quantidade de recursos (memória, CPU, conexões, espaço em disco) que um usuário ou processo pode consumir. Um atacante explora isso enviando requisições malformadas ou em grande volume para esgotar os recursos disponíveis, causando indisponibilidade do serviço.

Example

Um servidor web aceita uploads sem limite de tamanho ou número simultâneo de conexões. Um atacante envia centenas de uploads gigantescos ou mantém conexões abertas indefinidamente, preenchendo a memória e o disco até o servidor travar e ficar inacessível para usuários legítimos.

How to mitigate

Implemente limites explícitos: tamanho máximo de requisição/upload, timeout de conexão, máximo de conexões simultâneas, rate limiting. Monitore consumo de recursos e configure alertas. Use pools de conexão e libere recursos automaticamente após uso.
