Lab Walkthrough Video:

The attacker might not have any user-level access to the web application. However, this does not mean that the application cannot be attacked remotely. Remote Code Execution vulnerabilities could be triggered even by unauthenticated users.

In the exercise below, the attacker is not authenticated to the web application and needs to find a remote code execution attack to execute arbitrary commands on the server.

TestLink is web-based test management and test execution system. It enables quality assurance teams to create and manage their test cases as well as to organize them into test plans. These test plans allow team members to execute test cases and track test results dynamically.

Testlink (< v1.9.17) is vulnerable to a Remote Code Execution documented in CVE-2018-7466.

The following information may be helpful in exploiting the vulnerability:

Database nameapp
Database Admin Userpentester
Database Admin Passwordpassword1

Objective: Your task is to find and exploit this vulnerability.

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  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.
