SkyTower CTF Walkthrough

VM Author Description

This CTF was designed by Telspace Systems for the CTF at the ITWeb Security Summit and BSidesCPT (Cape Town). The aim is to test intermediate to advanced security enthusiasts in their ability to attack a system using a multi-faceted approach and obtain the “flag”.
You will require skills across different facets of system and application vulnerabilities, as well as an understanding of various services and how to attack them. Most of all, your logical thinking and methodical approach to penetration testing will come into play to allow you to successfully attack this system. Try different variations and approaches. You will most likely find that automated tools will not assist you.

Introduction Hello humans! I have been busy working preparing myself for the CTP Course and wanted to share my experience.
Just a quick disclaimer , i am not an expert exploit developer so maybe i have made some mistakes and certainly there are better ways to do the things but hey we must Try harder. In this post we will combine some exploitation methods to make a reliable vulnerability for RSP Mp3 OCX on Windows XP Sp3 (IE 7).
I know the software are outdated and not anything new but We must learn to walk before we can run. 
Environment Victim MachineWindows XP Sp3 with Internet Explorer 7Vulnerable ApplicationImmunity Debuggermona.py Attacker  Metasploit Framework Good Editor To register the vulnerable application you must run the register.bat and set the Internet Explorer Security level to LOW for Local Intranet.
Exploitation 101 If you are preparing for OSCE i assume you know basic exploit development so i wont explain in details the exploitation methods. I will focus on the combin…
