Challenge Overview

You are hired by a company as a security consultant in a cybersecurity firm. The system administrator in the firm recently created groups and added users to the machine. He has instructed that a pentest be done on the machine to see whether new changes can result in low-level users getting unintentional root access. Your target machine is running on Linux Ubuntu with an IP address of 10.10.1.14. You have user-level SSH access to the machine, and the credentials are Crawley and MXQtE$#7*1a. Your mission is to get root access to the system, find the flag.txt file, and submit the flag value. By completing this task, you will gain hands-on knowledge in Module 06: System Hacking and Privilege Escalation Techniques.

What You Will Learn

  • Enumerating a Linux system after gaining initial SSH user-level access.
  • Identifying misconfigured groups.
  • SUID files, and privilege escalation vectors.
  • Exploiting weak permissions or improper user-group assignments to gain root access.
  • Performing local privilege escalation techniques on Ubuntu systems.
  • Locating sensitive files (e.g., flag.txt) after successfully escalating privileges.
