Once credentials are obtained, the attacker can log in and attempt to escalate their privileges on the web server.

What or web technologies did your initial Nmap scan reveal?

After establishing a foothold as the chris user, the path to root access involves several sophisticated techniques. hackfail.htb

If you are following a specific local lab, a custom machine, or perhaps a misspelling of a known box (like or "Fail" ), a proper write-up should follow a professional penetration testing methodology. 1. Information Gathering & Reconnaissance

HackFail HTB: A Comprehensive Walkthrough HackFail is an Easy-rated Linux machine on Hack The Box that emphasizes the importance of secure coding practices and proper configuration of development environments. It provides an excellent playground for learning about Gitea vulnerabilities, Docker escapes, and exploiting misconfigured automation tools. 🔍 Phase 1: Reconnaissance & Enumeration python3 -c 'import pty; pty

Send the exploit payload via a POST or GET request using curl or Burp Suite to trigger a reverse shell:

The initial foothold on rarely involves a simple "click and win" exploit. It often requires chaining multiple vulnerabilities.

As I dug deeper into the website, I discovered a peculiar upload feature, allowing users to submit their own files. My curiosity piqued, I wondered if this could be a potential entry point. I recalled the concept of Server-Side Request Forgery (SSRF) and decided to investigate further. By manipulating the upload process, I aimed to trick the server into revealing sensitive information.

At each hop, the attacker used low-skill, well-known techniques — but combined they produced a total compromise.

file), enumerate the system for misconfigured SUID binaries or kernel exploits to reach "Root".

If /var/run/docker.sock is accessible, you can use it to spawn a new container that mounts the host's root filesystem. 👑 Phase 4: Privilege Escalation to Root
