If you'd like to dive deeper into any of these steps, I can provide: The used for initial discovery. A Python script to automate the Gitea hook exploit. The Fail2Ban configuration details for the root exploit.
Since direct uploads to the target might be restricted, use your attacker machine to host the binary and download it:
# Fast aggressive port discovery nmap -p- --min-rate 5000 -Pn -oN nmap_initial.txt # Targeted service and script scanning nmap -sC -sV -p 22,80,443 -oN nmap_detailed.txt Use code with caution. The scan reveals the following key entry points: hackfail.htb
During enumeration, you locate hardcoded credentials or a reusable SSH key inside a backup folder or a configuration file belonging to a specific user (e.g., developer or sysadmin ).
Look for standard ports like 80 (HTTP) , 443 (HTTPS) , or 22 (SSH) . 2. Web Enumeration If port 80/443 is open, explore the web application: If you'd like to dive deeper into any
Analyzing scheduled tasks (/etc/crontab) might reveal scripts that can be modified or that run from a world-writable directory.
Send the exploit payload via a POST or GET request using curl or Burp Suite to trigger a reverse shell: Since direct uploads to the target might be
nmap -sV hackfail.htb
