Processamento inseguro de XML externo (XXE)

Ocorre quando uma aplicação processa XML sem desabilitar a resolução de entidades externas, permitindo que um atacante injete referências a arquivos locais ou recursos remotos. O parser XML carrega esses recursos e expõe seu conteúdo ou causa negação de serviço, comprometendo confidencialidade e disponibilidade.

Example

Um endpoint de API aceita XML do usuário e o processa com um parser padrão. Um atacante envia um payload XXE que referencia `/etc/passwd` via entity declaration, e o parser retorna o conteúdo do arquivo na resposta ou em logs. Alternativa: bomb XML que incha exponencialmente, travando o servidor.

How to mitigate

Desabilite explicitamente entidades externas e DTDs no parser XML (ex: `XMLConstants.FEATURE_SECURE_PROCESSING` em Java; `LIBXML_DISABLE_ENTITY_LOADER` em PHP). Valide e sanitize entrada XML; prefira JSON quando possível. Teste com payloads XXE conhecidos.
