Mecanismo fraco de recuperação de senha

A aplicação usa um processo de recuperação de senha insuficientemente seguro, permitindo que um atacante redefina a senha de outro usuário sem autenticação adequada. Isso acontece quando perguntas de segurança são previsíveis, tokens de recuperação não expiram, ou a validação de identidade é inadequada — abrindo caminho para takeover de conta.

Ejemplo

Um banco que envia um link de reset com token válido por 30 dias, ou um e-commerce que valida recuperação apenas perguntando a data de nascimento do cadastro (informação frequentemente pública). Um atacante consegue acessar contas alheias explorando essas fraquezas.

Cómo mitigar

Use tokens criptograficamente fortes e com expiração curta (15-60 min), exija confirmação em múltiplos canais (SMS + email), implemente rate limiting para tentativas de reset, e evite perguntas de segurança previsíveis ou públicas. Valide a identidade com dados realmente privados ou biometria quando possível.
