Falhas do tipo CWE-502

2.669 resultados

Desserialização de dados não confiáveis

A aplicação converte dados recebidos de fontes externas (requisições, arquivos, rede) de volta para objetos em memória sem validar se o conteúdo é legítimo. Um atacante pode enviar dados malformados ou maliciosos que, ao serem desserializados, executam código arbitrário ou alteram o comportamento da aplicação.

Exemplo

Um servidor Java que desserializa objetos vindo de um cliente usando ObjectInputStream sem verificar a origem. Um atacante envia um objeto serializado contendo uma gadget chain que executa comandos do sistema operacional quando desserializado.

Como mitigar

Valide rigorosamente o tipo e estrutura dos dados antes de desserializar; use bibliotecas modernas que restringem quais classes podem ser desserializadas (com allowlists); considere alternativas como JSON com parsers estritamente tipados ao invés de serialização nativa de linguagem.
