Adminer Arbitrary File Read
cve-2021 | Level: Easy | Total Lab Runs: 0 | Premium Lab |
In this lab environment, the user will access a Kali GUI instance. A vulnerable machine running Adminer is deployed on http://demo.ine.local.
Adminer is a popular open-source web-based database management tool written in PHP. However, Adminer versions 1.12.0 to 4.6.2 suffer from Improper Access Control (fixed in version 4.6.3) that allows an attacker to achieve Arbitrary File Read on the remote server by requesting the Adminer to connect to a remote MySQL database.
This vulnerability has been assigned the CVE id CVE-2021-43008.
A vulnerable version of Adminer is installed on the target machine. Your task is to exploit the Arbitrary File Read vulnerability in Adminer to read and exfiltrate local files to the database.
The following details might be useful:
The database consists of an empty table named “lfr_sink_table”.
Objective: Exploit the Arbitrary File Read vulnerability in Adminer (v4.6.2) to read and exfiltrate local files to the database. Read the flag present in the system root directory.
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a root terminal of a Kali instance.
- Your Kali has an interface with IP address 192.X.Y.2. Run "ip addr" to know the values of X and Y.
- The target server should be located at the IP address 192.X.Y.3.
- Do not attack the gateway located at IP address 192.X.Y.1

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email firstname.lastname@example.org clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
