About XXE Vulnerabilities

XML External Entity (XXE) injection is a web security vulnerability that allows an attacker to interfere with an application's processing of XML data. It often allows an attacker to:

View files on the application server (local file disclosure)
Interact with internal systems (SSRF - Server-Side Request Forgery)
Perform denial-of-service attacks
Execute remote code in some contexts

XXE Attack Types:

Basic XXE: Direct entity expansion
File Read XXE: Reading local files
SSRF XXE: Making internal network requests
Blind XXE: Out-of-band data exfiltration
Error-Based XXE: Extracting data via errors

Prevention Methods:

Disable XML external entity processing
Use less complex data formats like JSON
Implement proper input validation
Use XML schema validation
Update XML processors and libraries

Testing Methodology:

Identify XML input points (APIs, file uploads, etc.)
Test with basic XXE payloads
Attempt file read operations
Test for SSRF capabilities
Check for blind XXE vulnerabilities
Document findings and remediation steps
