SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical security risks associated with real-time bidirectional communication, specifically identifying vulnerabilities like Cross-Site WebSocket Hijacking (CSWSH), insecure authentication, and improper channel authorization.

Core Features & Use Cases

  • Origin Validation Testing: Detects if the server fails to validate the Origin header, which could allow unauthorized third-party websites to hijack user sessions.
  • Injection Surface Identification: Probes for SQL, NoSQL, Command, and Template injection surfaces within WebSocket message fields.
  • Use Case: A security researcher can use this skill to audit a real-time chat application to ensure that users cannot subscribe to private channels belonging to other users or tenants.

Quick Start

Use the websocket-security skill to audit the target endpoint wss://api.example.com/v1/realtime for origin validation and channel authorization flaws.

FAQPage Schema
How do I test WebSocket endpoints for Cross-Site WebSocket Hijacking vulnerabilities?

Testing WebSocket origin validation involves checking if the server rejects unauthorized Origin headers. This skill probes the target endpoint to detect missing origin verification, which leaves real-time communication channels vulnerable to session hijacking by malicious third-party sites.

What is the best way to check WebSocket authentication and channel authorization controls?

The best way to check WebSocket authentication is to probe the target endpoint for enforcement gaps. This skill validates authentication mechanisms and channel-level authorization to identify tenant isolation failures where users might access private channels belonging to others.

How do I identify injection surfaces within WebSocket message fields?

Identifying WebSocket injection surfaces requires probing message fields with malicious payloads. This skill tests real-time communication inputs for SQL, NoSQL, Command, and Template injection vulnerabilities to uncover insecure data handling within the bidirectional message stream.

Can I use this for penetration testing real-time chat applications without disrupting system stability?

Yes, you can use this for penetration testing real-time chat applications safely. The skill requires authorized target scope and strictly adheres to non-destructive probing policies, ensuring system stability is maintained while auditing WebSocket security controls.

When do I need to audit WebSocket security controls for tenant isolation failures?

You need to audit WebSocket security controls for tenant isolation failures when securing multi-tenant real-time applications. This skill ensures users cannot subscribe to private channels belonging to other tenants by validating channel-level authorization across the communication protocol.
