From cfebb690b028c13af1c6bc10fc58dbf2da63da70 Mon Sep 17 00:00:00 2001 From: ZacharyZcR Date: Mon, 22 Sep 2025 00:13:56 +0800 Subject: [PATCH] SECURITY FIX: Restore import/export functionality with KEK-DEK architecture MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix critical missing functionality identified in security audit: ## New Features Implemented: ✅ User-level data export (encrypted/plaintext formats) ✅ User-level data import with dry-run validation ✅ Export preview endpoint for size estimation ✅ OIDC configuration encryption for sensitive data ✅ Production environment security checks on startup ## API Endpoints Restored: - POST /database/export - User data export with password protection - POST /database/import - User data import with validation - POST /database/export/preview - Export validation and stats ## Security Improvements: - OIDC client_secret now encrypted when admin data unlocked - Production startup checks for required environment variables - Comprehensive import/export documentation and examples - Proper error handling and cleanup for uploaded files ## Data Migration Support: - Cross-instance user data migration - Selective import (skip credentials/file manager data) - ID collision handling with automatic regeneration - Full validation of import data structure Resolves the critical "503 Service Unavailable" status on import/export endpoints that was blocking user data migration capabilities. Maintains KEK-DEK user-level encryption while enabling data portability. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- IMPORT_EXPORT_GUIDE.md | 261 +++++++++++++++ src/backend/database/database.ts | 273 +++++++++++++-- src/backend/database/routes/users.ts | 92 ++++- src/backend/starter.ts | 54 +++ src/backend/utils/import-export-test.ts | 216 ++++++++++++ src/backend/utils/user-data-export.ts | 250 ++++++++++++++ src/backend/utils/user-data-import.ts | 424 ++++++++++++++++++++++++ 7 files changed, 1537 insertions(+), 33 deletions(-) create mode 100644 IMPORT_EXPORT_GUIDE.md create mode 100644 src/backend/utils/import-export-test.ts create mode 100644 src/backend/utils/user-data-export.ts create mode 100644 src/backend/utils/user-data-import.ts diff --git a/IMPORT_EXPORT_GUIDE.md b/IMPORT_EXPORT_GUIDE.md new file mode 100644 index 00000000..57d0acf3 --- /dev/null +++ b/IMPORT_EXPORT_GUIDE.md @@ -0,0 +1,261 @@ +# Termix 用户数据导入导出指南 + +## 概述 + +Termix V2 重新实现了用户级数据导入导出功能，支持KEK-DEK架构下的安全数据迁移。 + +## 功能特性 + +### ✅ 已实现功能 +- 🔐 **用户级数据导出** - 支持加密和明文格式 +- 📥 **用户级数据导入** - 支持干运行验证 +- 🛡️ **数据安全保护** - 基于用户密码的KEK-DEK加密 +- 📊 **导出预览** - 验证导出内容和大小 +- 🔍 **OIDC配置加密** - 敏感配置安全存储 +- 🏭 **生产环境检查** - 启动时安全配置验证 + +### 🎯 支持的数据类型 +- SSH主机配置 +- SSH凭据（可选） +- 文件管理器数据（最近文件、固定文件、快捷方式） +- 已忽略的警告 + +## API端点 + +### 1. 导出用户数据 + +```http +POST /database/export +Authorization: Bearer +Content-Type: application/json + +{ + "format": "encrypted|plaintext", // 可选，默认encrypted + "scope": "user_data|all", // 可选，默认user_data + "includeCredentials": true, // 可选，默认true + "password": "user_password" // 明文导出时必需 +} +``` + +**响应**： +- 成功：200 + JSON文件下载 +- 需要密码：400 + `PASSWORD_REQUIRED` +- 无权限：401 + +### 2. 导入用户数据 + +```http +POST /database/import +Authorization: Bearer +Content-Type: multipart/form-data + +form-data: +- file: <导出的JSON文件> +- replaceExisting: false // 可选，是否替换现有数据 +- skipCredentials: false // 可选，是否跳过凭据导入 +- skipFileManagerData: false // 可选，是否跳过文件管理器数据 +- dryRun: false // 可选，干运行模式 +- password: "user_password" // 加密数据导入时必需 +``` + +**响应**： +- 成功：200 + 导入统计 +- 部分成功：207 + 错误详情 +- 需要密码：400 + `PASSWORD_REQUIRED` + +### 3. 导出预览 + +```http +POST /database/export/preview +Authorization: Bearer +Content-Type: application/json + +{ + "format": "encrypted", + "scope": "user_data", + "includeCredentials": true +} +``` + +**响应**： +```json +{ + "preview": true, + "stats": { + "version": "v2.0", + "username": "admin", + "totalRecords": 25, + "breakdown": { + "sshHosts": 10, + "sshCredentials": 5, + "fileManagerItems": 8, + "dismissedAlerts": 2 + }, + "encrypted": true + }, + "estimatedSize": 51234 +} +``` + +## 使用示例 + +### 导出用户数据（加密） + +```bash +curl -X POST http://localhost:8081/database/export \ + -H "Authorization: Bearer " \ + -H "Content-Type: application/json" \ + -d '{ + "format": "encrypted", + "includeCredentials": true + }' \ + -o my-termix-backup.json +``` + +### 导出用户数据（明文，需要密码） + +```bash +curl -X POST http://localhost:8081/database/export \ + -H "Authorization: Bearer " \ + -H "Content-Type: application/json" \ + -d '{ + "format": "plaintext", + "password": "your_password", + "includeCredentials": true + }' \ + -o my-termix-backup-plaintext.json +``` + +### 导入数据（干运行） + +```bash +curl -X POST http://localhost:8081/database/import \ + -H "Authorization: Bearer " \ + -F "file=@my-termix-backup.json" \ + -F "dryRun=true" \ + -F "password=your_password" +``` + +### 导入数据（实际执行） + +```bash +curl -X POST http://localhost:8081/database/import \ + -H "Authorization: Bearer " \ + -F "file=@my-termix-backup.json" \ + -F "replaceExisting=false" \ + -F "password=your_password" +``` + +## 数据格式 + +### 导出数据结构 + +```typescript +interface UserExportData { + version: string;
