How to do it...
- If possible, avoid the use of XML and prefer less complex formats, such as JSON.
- If XML use is mandatory, disable the use of external entities in all parsers used by the application.
- If a certain functionality requires the use of external entities to load files or access remote resources, consider reimplementing the functionality using other technologies.
- Always validate data provided by users and third parties on both client and server sides. For data in XML format, using a white list of allowed words/elements and characters is a good option.
- Keep the XML interpreter (usually integrated into the development tools) adequately patched and updated to prevent and fix common vulnerabilities.
