Description

[BLUF] This video demonstrates a CTF challenge involving an Ubuntu Server with SSH and a Python web application, focusing on reconnaissance and initial enumeration. 0:30

Key Takeaways:
• The attacker begins with an Nmap scan using default scripts and version detection to identify open ports and services. 0:17
• The scan reveals two open ports: SSH on port 22 and an HTTP server on port 5000. 0:35
• The SSH banner indicates the target is running an Ubuntu Server, providing initial OS fingerprinting. 0:39
• The presence of port 5000 suggests a Python-based web application, likely Flask or similar, which becomes the primary attack vector. 0:45

The challenge emphasizes the importance of thorough service enumeration before attempting exploitation. Understanding the underlying technology stack is crucial for identifying potential vulnerabilities in web applications.

Sources:

  • 0:30 Nmap scan execution and initial findings.
  • 0:35 Identification of open ports SSH and HTTP.
  • 0:39 SSH banner analysis revealing Ubuntu OS.
  • 0:45 Identification of Python web server on port 5000.

what's going on YouTube this is IPC and be doing chemistry from hack the box and I recorded this video without any prep because when I solved this four or five months ago I left myself a note saying it would be fun doing Blind and since I'm going to add it semi blind let's not spoil anything here and just jump right in as always we start with the N map so- SCC for default scripts SV enumerate versions - VV for double rebost this gives us things like the TTL OA output all formats put in the end map directory and call it chemistry and then the IP address of 10101 11.38 this can take sub typ to run so I've already ran it looking at the results we have just two ports open the first one being SSH on Port 22 and the banner tells us it's an auntu server and then we have something on Port 5000 and…
