该漏洞可通过利用一个 JWT 令牌来绕过身份验证，其 `SharedSecret` 为空，从而获得对数据库的访问权限。
{% endhint %}
#### 访问数据库
连接到 InfluxDB 后，列出可用的数据库：
```sql
SHOW DATABASES;
```
选择 `devzat` 数据库并探索用户数据。首先列出测量项（表）：
```sql
SHOW MEASUREMENTS;
```
该 **`用户`** 表包含有用信息。要探索该测量项的列，请运行：
```sql
SHOW FIELD KEYS FROM "user";
```
显示前 10 条结果，来自 `用户` 表：
```sql
SELECT * FROM "user" LIMIT 10;
```

## 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/ports-and-services/influxdb-8086.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.
