Falhas do tipo CWE-617
556 resultadosAsserção acessível ao atacante
É quando o código contém uma asserção (assertion) que pode ser disparada por um atacante, causando travamento ou parada da aplicação. Diferente de asserções usadas apenas em desenvolvimento, essas chegam à produção e podem ser exploradas para negar serviço.
Exemplo
Um servidor web valida entrada do usuário com assert(tamanho_entrada < 1000). Um atacante envia payload grande, a asserção falha e o processo morre, deixando o serviço indisponível para outros usuários.
Como mitigar
Remova ou desative asserções em código de produção; use exceções tratáveis em vez de assertions para validações que dependem de entrada do usuário. Compile com flags que desabilitam assertions (-da em Java) antes de deployar.
