Desserialização de dados não confiáveis

A aplicação reconstrói objetos a partir de dados recebidos (JSON, XML, binário) sem validar se o resultado é seguro. Um atacante pode injetar código malicioso ou estruturas que exploram o processo de desserialização para executar ações arbitrárias no servidor ou cliente.

Ejemplo

Um serviço Java desserializa um objeto enviado pelo usuário usando ObjectInputStream sem filtros. O atacante envia um payload serializado que, ao ser reconstituído, executa comandos do sistema. Cenário comum: aplicações legadas que confiam em dados de rede ou arquivos sem inspeção.

Cómo mitigar

Valide e filtre dados antes de desserializar — use listas de classes permitidas (whitelisting), implemente validação de schema, e prefira formatos simples (JSON com parse restritivo) em vez de binários com lógica automática. Para linguagens críticas como Java, use bibliotecas seguras ou desabilite gadgets perigosos.
