Autenticação inadequada sujeita a falsificação de identidade

Ocorre quando o mecanismo de autenticação é implementado de forma fraca ou incompleta, permitindo que um atacante se faça passar por outro usuário ou sistema sem precisar das credenciais legítimas. O risco é grave: qualquer um pode ganhar acesso não autorizado simplesmente contornando ou falsificando a identidade.

Ejemplo

Um app que autentica usuários apenas verificando um header HTTP customizado (tipo 'X-User-ID: 123') sem validação criptográfica real. Um atacante muda esse header para 'X-User-ID: admin' e consegue acesso à conta administrativa. Ou um serviço que aceita requisições apenas porque vêm de um IP específico, sem verificar certificados ou assinaturas.

Cómo mitigar

Use protocolos de autenticação estabelecidos (OAuth 2.0, JWT com assinatura, SAML) em vez de inventar o seu. Sempre valide credenciais no servidor com mecanismos criptográficos (hash, assinatura digital, certificados). Nunca confie em headers HTTP, IPs ou tokens não assinados como prova única de identidade.
