Falta de limitação em tentativas de autenticação

É quando a aplicação não restringe adequadamente quantas vezes um atacante pode tentar adivinhar credenciais (senha, PIN, código MFA). Sem limite de tentativas ou delay entre elas, força bruta fica viável: o atacante testa combinações até encontrar a senha correta.

Ejemplo

Um formulário de login que aceita requisições ilimitadas sem rate limiting — alguém escreve um script que testa 10 mil senhas por segundo contra uma conta específica até acertar. Ou um endpoint de recuperação de senha que valida códigos sem contar quantas tentativas erradas já houve.

Cómo mitigar

Implemente rate limiting (máximo de tentativas por IP/usuário em janela de tempo), aumente delay exponencial entre tentativas falhadas, bloqueie a conta ou IP temporariamente após N falhas, e use CAPTCHA ou MFA para dificultar automação. Log de tentativas suspeitas é essencial para detecção.
