WebSocket Injection Scanner
Tests for injection attacks through WebSocket messages.
What is WebSocket Injection?
WebSocket Injection vulnerabilities occur when data received through WebSocket connections is used unsafely in SQL queries, command execution, HTML rendering, or other contexts. WebSocket message content bypasses traditional input validation applied to HTTP requests, making injection more likely.
Why is This Important?
WebSocket traffic often receives less security scrutiny than HTTP. Developers may skip input validation assuming WebSocket is 'internal.' WAFs typically don't inspect WebSocket messages. This creates injection opportunities through an overlooked channel, potentially with real-time exploitation capability.
How It Works
1. Attack Surface Mapping
Identifies complex attack vectors including race conditions, desync points, and logic flaws in your application.
2. Advanced Exploitation
Executes sophisticated attack techniques that bypass traditional security controls and detection mechanisms.
3. Impact Assessment
Demonstrates real-world impact with detailed exploitation chains and business risk analysis.
Key Capabilities
Expert-level security testing for sophisticated vulnerabilities that evade traditional scanning tools.
- Race condition and timing attack detection
- Request smuggling and desync analysis
- Business logic flaw identification
- Chained exploit development
- Protocol-level vulnerability testing
Frequently Asked Questions
What injection types affect WebSocket?
All standard injection types: SQL injection through WebSocket parameters, XSS if messages are rendered in HTML, command injection if messages trigger system operations, NoSQL injection, and even LDAP or other backend injections. The vector changes, the vulnerabilities don't.
Why is WebSocket injection often missed?
Reasons: WebSocket testing is less common, WAFs don't inspect WebSocket traffic, input validation may not be applied to WebSocket message parsers, developers assume binary protocols are safer, and real-time nature makes logging/monitoring harder.
How do I test for WebSocket injection?
Testing approach: use WebSocket clients (wscat, browser DevTools) to send injection payloads, intercept with Burp Suite's WebSocket support, fuzz all JSON/message fields with injection patterns, test for blind injection via timing, and review server-side message handling code.
How do I secure WebSocket message handling?
Apply the same security controls as HTTP: validate and sanitize all message content, use parameterized queries, encode output, implement message schema validation, log WebSocket activity for detection, and include WebSocket in security testing and WAF coverage.
