# Testing for XXE Injection Vulnerabilities
## When to Use
- During authorized penetration tests when the application processes XML input (SOAP APIs, file uploads, RSS feeds)
- When testing APIs that accept `Content-Type: application/xml` or `text/xml`
- For assessing XML parsers in file upload functionality (DOCX, XLSX, SVG, PDF)
- 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
