Injeção de Entidade Externa XML (XXE)

Ocorre quando a aplicação parseia XML sem desabilitar o processamento de entidades externas, permitindo que um atacante injete referências a arquivos locais, servidores internos ou execute ataques de negação de serviço. O risco é crítico: vazamento de dados sensíveis, acesso a sistemas internos ou consumo excessivo de recursos.

Exemplo

Uma API que aceita XML em uma requisição POST parse o conteúdo diretamente com a biblioteca padrão. Um atacante envia um payload como `<!DOCTYPE foo [<!ENTITY xxe SYSTEM "file:///etc/passwd">]>` e consegue ler arquivos do servidor.

Como mitigar

Desabilite explicitamente o processamento de entidades externas na configuração do parser XML (ex: `XMLConstants.ACCESS_EXTERNAL_DTD` em Java, `resolve_external_entities = False` em Python). Valide e sanitize entrada XML antes do parse, prefira APIs mais seguras ou formatos como JSON quando possível.
