Desserialização de dados não confiáveis

A aplicação reconstrói objetos a partir de dados serializados (JSON, XML, binário) recebidos de fontes externas sem validar adequadamente se o conteúdo é legítimo. Um atacante pode injetar código malicioso ou objetos especialmente crafted que são executados durante a desserialização, comprometendo toda a aplicação.

Example

Um servidor Java desserializa objetos recebidos em requisições HTTP usando ObjectInputStream, sem verificar a classe ou origem dos dados. Um atacante envia um objeto serializado contendo uma cadeia de gadgets (RCE via biblioteca como Apache Commons Collections) que é executada assim que o objeto é reconstruído em memória.

How to mitigate

Valide e liste explicitamente as classes que podem ser desserializadas (whitelist). Para JSON/XML, use parsers que não executem código (como JSON simples, evite eval). Considere alternativas seguras como Protocol Buffers ou MessagePack, e mantenha bibliotecas críticas atualizadas.
