Plan

Penetration Testing Implementation Plan

Project Overview

XibeCode is a sophisticated AI-powered autonomous coding assistant with multiple attack surfaces:

  • CLI Tool (Node.js/TypeScript)
  • WebUI Server (HTTP + WebSocket)
  • Frontend (React/Vite)
  • Documentation Site (Next.js)
  • Electron Desktop App
  • Browser Automation (Playwright/agent-browser)

Scope Definition

In-Scope

  1. WebUI Server (src/webui/server.ts)

    • REST API endpoints
    • WebSocket connections
    • File operations and path traversal
    • Authentication/authorization (if any)

  2. Frontend Application (webui/src/)

    • XSS vulnerabilities
    • Client-side security issues
    • Input validation

  3. CLI Security

    • Command injection
    • File system access
    • API key handling

  • Git command injection

2. Frontend (webui/src/)

Entry Points:

  • User inputs (chat, file paths, commands)
  • File upload/download
  • Monaco editor
  • Terminal emulator

Potential Vulnerabilities:

  • XSS via message rendering
  • File path manipulation
  • Insecure storage (localStorage/sessionStorage)
  • WebSocket message tampering

3. CLI Tool

Entry Points:

  • Command-line arguments
  • Configuration files

  • File write/overwrite attacks
  • Insecure API key storage
  • MCP server configuration tampering

4. Documentation Site (site/)

Entry Points:

  • Search API
  • Chat API (if AI-powered)
  • MongoDB connections

Potential Vulnerabilities:

  • NoSQL injection

Testing Methodology

Phase 1: Reconnaissance (Manual Analysis)

  1. Code Review

    • Read src/webui/server.ts - API endpoints
    • Review src/core/tools.ts - Command execution
    • Check src/utils/safety.ts - Security controls
    • Examine src/core/editor.ts - File operations

  2. Configuration Analysis

    • Check .env.example files
    • Review package.json dependencies
    • Analyze MCP server config format

  3. Attack Surface Mapping

    • List all HTTP endpoints
    • Map WebSocket message types
    • Identify file I/O operations
    • Document command execution paths

Phase 2: Automated Testing (agent-browser)

Using agent-browser to interact with the WebUI:

  1. Start the Application

    # Terminal 1: Start WebUI
xibecode ui --port 3847

# Terminal 2: Run pentest automation
agent-browser open http://localhost:3847

  2. Test Scenarios

    • Path traversal attempts
    • Command injection payloads
    • XSS injection
    • CORS validation
    • WebSocket fuzzing

Phase 3: Manual Exploitation

  1. Path Traversal Testing

    • Test /api/files/read with ../../../etc/passwd
    • Test /api/files/raw with absolute paths
    • Test file tree endpoint with malicious paths

  2. Command Injection

    • Test terminal creation with malicious cwd
    • Test terminal input with shell metacharacters
    • Test git commands via API

  3. Authentication Testing

    • Verify if any endpoints require auth
    • Test session management
    • Check for IDOR vulnerabilities

  4. XSS Testing

    • Inject payloads into chat messages
    • Test markdown rendering
    • Test file content display

  5. Configuration Attacks

    • Attempt to overwrite MCP config
    • Test .env file manipulation
    • Try to read sensitive files

Phase 4: Documentation Site Testing

  1. Search API

    • Test for NoSQL injection
    • Check for SSRF

  2. Chat API

    • Test AI prompt injection
    • Check for unauthorized access

Risk Assessment Framework

Severity Levels

  • Critical (9-10): Remote code execution, authentication bypass
  • High (7-8): Path traversal, command injection, XSS
  • Medium (4-6): Information disclosure, CORS issues
  • Low (1-3): Verbose errors, version disclosure
  • Info (0): Best practice recommendations

Impact Categories

  • Confidentiality: Can attacker read sensitive data?
  • Integrity: Can attacker modify data/code?
  • Availability: Can attacker disrupt service?

Architectural Changes

Files to Analyze

  1. src/webui/server.ts - Main API server (2600+ lines)
  2. src/core/tools.ts - Tool execution and permissions
  3. src/utils/safety.ts - Security checks
  4. src/core/editor.ts - File editing
  5. webui/src/ - Frontend components
  6. site/app/api/ - Next.js API routes

No Code Changes Required

This is a read-only security assessment. We will:

  • ✅ Document vulnerabilities
  • ✅ Provide proof-of-concepts
  • ✅ Recommend fixes
  • ❌ Not modify application code

Potential Risks

High-Risk Areas

  1. Python PTY Bridge (lines 1002-1050 in server.ts)

    • User-controlled cwd parameter
    • Direct shell execution

  2. File Operations

    • /api/files/read - Path traversal risk
    • /api/files/raw - Binary file access
    • /api/files/tree - Directory traversal
    • /api/env - Environment variable manipulation

  3. Command Execution

    • run_command tool in tools.ts
    • Git command execution
    • Test runner execution

  4. MCP Configuration

    • API key stored in config only

  2. CORS Configuration

    • Wildcard origin (*)

  3. WebSocket Security

    • No authentication on WS connections
    • Message validation unclear

Low-Risk Areas

  1. Input Validation

    • Some path validation exists
    • Basic safety checks in place

  2. Error Handling

    • Try-catch blocks present
    • May expose verbose errors

Expected Findings Categories

  • Path traversal to sensitive files
  • Command injection
  • XSS in chat/markdown

Medium

  • CORS misconfiguration
