Mecanismo fraco de recuperação de senha

A aplicação oferece um fluxo de recuperação de senha (esqueci minha senha) que é facilmente contornável ou previsível. Um atacante pode adivinhar perguntas de segurança, interceptar links de reset, reusar tokens, ou explorar validações fracas para assumir contas alheias sem conhecer a senha original.

Exemplo

Um site envia um link de reset de senha por e-mail, mas o token nunca expira e é simplesmente o ID do usuário codificado em base64. Um atacante pode reutilizar tokens antigos ou gerar novos para qualquer usuário, resetando suas senhas à vontade.

Como mitigar

Implemente tokens de reset com alta entropia, validade curta (15-30 min), uso único, e vinculação ao IP/sessão. Valide a identidade antes do reset (OTP, e-mail de confirmação, desafio adaptativo). Registre e monitore tentativas anormais de recuperação.
