phpMyAdmin 4.8.1 RCE (CVE-2018-12613)
cve-2018 | Level: Easy | Total Lab Runs: 0 | Premium Lab |
What is phpMyAdmin?
phpMyAdmin is a free software tool written in PHP, intended to handle the administration of MySQL over the Web. phpMyAdmin supports a wide range of operations on MySQL and MariaDB. Frequently used operations (managing databases, tables, columns, relations, indexes, users, permissions, etc.) can be performed via the user interface, while you still have the ability to directly execute any SQL statement.
What is CVE-2018-12613?
An issue was discovered in phpMyAdmin 4.8.x before 4.8.2, in which an attacker can include (view and potentially execute) files on the server. The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages. An attacker must be authenticated, except in the "$cfg['AllowArbitraryServer'] = true" case (where an attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin) and the "$cfg['ServerDefault'] = 0" case (which bypasses the login requirement and runs the vulnerable code without any authentication).
In this lab environment, the user is going to get access to a Kali GUI instance. A phpMyAdmin instance vulnerable to an authenticated RCE vulnerability, identified by CVE-2018-12613, is running on the target server. It can be accessed using the tools installed on Kali at http://demo.ine.local.
Objective: Leverage the affected setup script functionality to exploit the RCE vulnerability as an unauthenticated user.
Use the following credentials to authenticate to the phpMyAdmin dashboard:
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 phpMyAdmin instance should be accessible on http://demo.ine.local.
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 email@example.com 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.
