# InfluxDB - 8086
8086 端口暴露了 InfluxDB 1.7.5 版本。目标受 InfluxDB 身份验证绕过漏洞影响：
**漏洞：**[CVE-2019-20933](https://nvd.nist.gov/vuln/detail/CVE-2019-20933)
{% embed url="" %}
{% hint style="info" %}
该漏洞允许通过利用一个 JWT 令牌来绕过身份验证，该令牌的 `SharedSecret` 为空，这使得可以访问数据库。
{% endhint %}
#### 访问数据库
一旦连接到 InfluxDB，列出可用的数据库：
```sql
SHOW DATABASES;
```
选择 `devzat` 数据库并探索用户数据。先列出测量项（表）：
```sql
SHOW MEASUREMENTS;
```
该 **`用户`** 表包含有用信息。要查看该测量项的列，请运行：
```sql
SHOW FIELD KEYS FROM "user";
```
显示来自 `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 dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
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 optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
