Falhas do tipo CWE-307

545 resultados

Falta de proteção contra tentativas excessivas de autenticação

A aplicação não limita ou não desacelera tentativas de login, permitindo que um atacante teste múltiplas credenciais rapidamente (força bruta, dicionário ou spray de senhas). Sem controle, a conta fica vulnerável a comprometimento, especialmente se senhas fracas forem usadas.

Exemplo

Um endpoint de login que aceita 10 mil requisições por segundo sem nenhuma restrição. Um atacante automatiza tentativas com senhas comuns contra mil usuários até acertar credenciais válidas em poucos minutos.

Como mitigar

Implemente rate limiting (máximo de tentativas por IP/usuário em período curto), atrasos progressivos (backoff exponencial) após falhas, bloqueio temporário de conta após N tentativas, e idealmente autenticação multifator para reduzir o dano de senhas comprometidas.
