# 通过定向扫描实现快速检测
通过定向扫描实现快速检测，PortSwigger Web Security Academy 实验笔记，包括利用流程、载荷测试、Burp Suite 验证以及修复上下文。
### 通过有针对性的扫描快速发现漏洞
#### 实验环境
这个实验包含一个漏洞，能够 **读取服务器上的任意文件**. / 目标是 **恢复以下内容： `/etc/passwd` 该文件的内容，且用时少于 10 分钟**.
由于这一时间限制，建议使用 **Burp Scanner** 而不是对整个应用进行全面审计。
#### 时间限制
* 从实验开始起，会启动一个 \*\*10 分钟计时器\*\*。
* 对整个站点进行扫描可能太慢。
* 因此更适合 **聪明地定位潜在易受攻击的入口点**.
#### 方法
1. **使用 Burp Proxy 拦截一个相关的 HTTP 请求** 。
快速分析请求逻辑，以识别一个有趣的端点。
通过 **Burp Scanner** 对此特定请求运行有针对性的扫描。
#### Burp 扫描配置
* 已选择的扫描类型： **爬取并审计**
* 模式： **快速扫描**
目标：快速识别可利用的攻击向量
#### 已识别漏洞
扫描显示一种类型为 **XML 注入（XInclude）**.
Burp Scanner 检测到的初始载荷：
{% code overflow="wrap" %}
```xml
```
{% endcode %}
这证实了服务器会处理 **XInclude** 实体，且不受限制。
#### 利用：读取 `/etc/passwd`
将载荷修改为包含一个本地系统文件：
{% code overflow="wrap" %}
```http
productId=
id>&storeId=1
```
{% endcode %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/web/essential-skills/fast-detection-with-targeted-scanning.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
