XXE Injection Scanner
Detects XML External Entity injection vulnerabilities in XML parsers.
What is XXE Injection?
XML External Entity (XXE) injection exploits vulnerable XML parsers that process external entity references. Attackers can define external entities that read local files, make network requests (SSRF), or cause denial of service. This affects any application that parses user-supplied XML.
Why is This Important?
XXE can read sensitive files (/etc/passwd, application configs), perform SSRF attacks to internal systems, exfiltrate data via out-of-band channels, and cause denial of service through recursive entity expansion (Billion Laughs attack).
How It Works
1. Web Crawling
Intelligent crawling discovers all endpoints, forms, parameters, and dynamic content across your web application.
2. Payload Injection
AI-powered payloads test each input vector for web vulnerabilities with context-aware attack patterns.
3. Response Analysis
Advanced analysis detects vulnerability signatures in responses, confirming exploitability with proof-of-concept.

Frequently Asked Questions
Where is XXE commonly found?
XML-based APIs, SOAP services, file upload features accepting XML/DOCX/SVG, RSS/Atom feed parsers, SAML implementations, and any XML processing functionality.
What's a blind XXE attack?
When the XML parser doesn't return entity contents in responses, attackers use out-of-band techniques to exfiltrate data via HTTP requests to attacker-controlled servers.
Can XXE read binary files?
Direct reading of binary files often fails, but techniques like PHP filters (php://filter/convert.base64-encode) can encode binary data for exfiltration.
How do I prevent XXE?
Disable external entity processing in your XML parser, use less complex data formats like JSON when possible, and validate/sanitize XML input.
