Challenge Overview

Bugs College is a cybersecurity training company. You are a penetration tester working on the security team at Bugs College. You have been assigned the task of performing a penetration test to ensure that the web server of the company is secure. You have to perform a penetration test on the web server and exploit the vulnerabilities found before reporting them to your superiors. Your target web server is running on Ubuntu with an IP address of 10.10.1.144. You are required to discover and exploit the web application vulnerabilities and perform various attack techniques to gain access to the web server machine and find the files flag.txt and root.txt. By completing this task, you will gain hands-on knowledge in web applications hacking and pen testing.

What You Will Learn

  • Service enumeration and reconnaissance, including identifying exposed services like NFS and FTP on the Ubuntu target (10.10.1.144).
  • Exploiting misconfigured NFS shares, particularly mounting open shares and understanding the security impact of the no_root_squash option.
  • Performing credential brute-forcing attacks, specifically using tools like Hydra to compromise FTP accounts.
  • Deploying and triggering a PHP reverse shell via FTP, demonstrating initial access techniques against a web server.
  • Executing Linux privilege escalation through NFS misconfiguration, by abusing no_root_squash to create a SUID bash binary and obtain root privileges, ultimately retrieving flag.txt and root.txt.
