- When evaluating SOAP-based web services for entity injection
- During security assessments of enterprise applications using XML configuration
Prerequisites
- Authorization: Written penetration testing agreement for the target
- Burp Suite Professional: For intercepting and modifying XML requests
- XXEinjector: Automated XXE exploitation tool (
