RickdiculouslyEasy: 1 - Walkthrough

It has been a long time since I've last posted anything off of Vulnhub. To be honest, I just haven't had too much time to dive into any of these VM's. However, g0tmi1k released a ton of new VM's so I wanted to check them out. One of which is was RickdiculouslyEasy: 1 made by Luke.

This VM is based off the tv show Rick and Morty. I, myself, am a fan of this show so I had to check it out. It turned out to be quite easy but I still had fun solving it. Below is my walkthrough on capturing all of the flags.

Elevate from Admin to NT Authority\SYSTEM

Elevate from Admin to NT Authority\SYSTEM


The other day I gained Administrative access to a windows machine. While I was enumerating around, I had the urge to escalate to the most powerful account on a Windows local instance: NT Authority\SYSTEM.

I realized there weren't a lot of posts online about it. I figured I'd give the steps I did in order to accomplish this task.

64Base - Walkthrough




It's been a while since I've been able to work on a vulnhub image. I started looking at recent releases and came across 64base. This VM has a Star Wars theme which is always great. Plus, it was 3mrgnc3's first public VM so I had to check it out!

Protostar - stack4

This is my fifth post on the Protostar series hosted by Exploit Exercises

We start off with understanding what is being asked of us:


About

Stack4 takes a look at overwriting saved EIP and standard buffer overflows.
This level is at /opt/protostar/bin/stack4
Hints
  • A variety of introductory papers into buffer overflows may help.
  • gdb lets you do “run < input”
  • EIP is not directly after the end of buffer, compiler padding can also increase the size.

Source code



#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
#include <string.h>

void win()
{
  printf("code flow successfully changed\n");
}

int main(int argc, char **argv)
{
  char buffer[64];

  gets(buffer);
}
