Processamento Inseguro de XML Externo (XXE)

Ocorre quando a aplicação processa XML sem desabilitar ou validar entidades externas, permitindo que um atacante injete referências a arquivos locais ou recursos remotos. O parser XML resolve essas entidades e expõe dados sensíveis ou permite ataques de negação de serviço.

Ejemplo

Um serviço web que aceita XML de upload processa um arquivo contendo <!DOCTYPE foo [<!ENTITY xxe SYSTEM "file:///etc/passwd">]>. O parser resolve a entidade e retorna o conteúdo do arquivo no erro ou resposta, ou um atacante injeta billion laughs attack para consumir memória do servidor.

Cómo mitigar

Desabilite explicitamente DTDs e entidades externas no parser XML (em Java, use XMLConstants.ACCESS_EXTERNAL_DTD = ""; em Python, use defusedxml ou desabilite resolve_entities; sempre valide e sanitize entrada XML contra schema predefinido).
