|
||
|
||
Adminer是一个PHP编写的开源数据库管理工具，支持MySQL、MariaDB、PostgreSQL、SQLite、MS SQL、Oracle、Elasticsearch、MongoDB等数据库。
|
||
|
||
在其版本1.12.0到4.6.2之间存在一处因为MySQL LOAD DATA LOCAL导致的文件读取漏洞。

||
## 漏洞环境
|
||
|
||
执行如下命令启动Web服务，其中包含Adminer 4.6.2：
|
||
|
||
```
|
||
docker compose up -d
|
||
```
|
||
|
||
服务启动后，在`http://your-ip:8080`即可查看到Adminer的登录页面。
|
||
|
||
## Exploit
|
||
|
||
使用[mysql-fake-server](https://github.com/4ra1n/mysql-fake-server)启动一个恶意的MySQL服务器。在Adminer登录页面中填写恶意服务地址和用户名`fileread_/etc/passwd`：
|
||
|
||
|
||
|
||
可见，我们已经收到客户端连接，读取到的文件`/etc/passwd`已保存至当前目录：
