Deputado Confuso (Proxy ou Intermediário Não Intencional)

Quando um componente intermediário (servidor, API, função, etc.) executa ações em nome de um cliente sem validar adequadamente quem realmente autorizou aquela ação, um atacante consegue explorar a confiança já estabelecida entre esse intermediário e outros sistemas. O intermediário acaba agindo como 'procurador involuntário' do atacante, realizando operações que o sistema final nunca autorizaria se a requisição viesse diretamente do atacante.

Example

Um servidor de cache proxy que aceita requisições GET de qualquer origem e as repassa a um serviço interno sem verificar se o cliente original deveria ter acesso àqueles dados. Um atacante faz o proxy buscar informações sensíveis do servidor interno e devolver para si, usando a confiança que o servidor interno tem no proxy.

How to mitigate

Valide a identidade e autorização do cliente original antes de repassar requisições para sistemas internos; use tokens ou assinaturas criptográficas que viagem junto com a requisição; implemente listas de origem segura (whitelist) rigorosas e autenticação mútua entre componentes intermediários e backends.
