Introduction to Binary Exploitation

Introduction to Binary Exploitation for Pen Testing

Binary exploitation is a technique used in computer security to exploit vulnerabilities in software applications. Penetration testers use binary exploitation to test the security of an application by trying to identify vulnerabilities and then exploiting them to gain unauthorized access to the system. This blog will provide an in-depth introduction to binary exploitation for pen testing, including examples, how-tos, and necessary tools and commands.

Binary Exploitation Basics

Before diving into binary exploitation, it is essential to have a basic understanding of how computers execute programs. When you run a program on a computer, the program code is loaded into memory and executed by the computer's CPU. The program's code is usually compiled into machine code, which consists of a series of instructions that the CPU can understand and execute.

Binary exploitation takes advantage of vulnerabilities in a program's code to modify the behavior of the program and execute arbitrary code. These vulnerabilities can include buffer overflows, format string vulnerabilities, integer overflows, and many others. By exploiting these vulnerabilities, an attacker can gain control over the program's behavior and potentially gain unauthorized access to the system.

Example of a Buffer Overflow Vulnerability

One of the most common types of vulnerabilities that can be exploited using binary exploitation is a buffer overflow. A buffer overflow occurs when a program tries to write data to a buffer that is too small, causing the data to overflow into adjacent memory locations. This can result in the program's behavior being modified or even causing a crash.

Let's take a look at a simple C program that is vulnerable to a buffer overflow:

#include <stdio.h> #include <string.h> void function(char *str) { char buffer[16]; strcpy(buffer, str); printf("buffer: %s\n", buffer); } int main() { char large_string[256]; int i; for (i = 0; i < 255; i++) { large_string[i] = 'A'; } large_string[255] = '\0'; function(large_string); return 0; }


This program takes a string as input, copies it into a buffer, and then prints the contents of the buffer. However, the buffer is only 16 bytes long, so if the input string is longer than 16 bytes, it will overflow into adjacent memory locations.

To exploit this vulnerability, we can create a payload that will overwrite the return address of the function with the address of our own code. We can then execute our code by returning to it instead of returning to the original function.

Let's take a look at how we can create this payload using Python and the pwntools library:

from pwn import * context.arch = 'amd64' # Address of the function we want to execute shellcode_addr = 0x4005b4 # Create a payload that overwrites the return address with our own address payload = b'A' * 16 payload += p64(shellcode_addr) # Send the payload to the program using a local process p = process('./vuln') p.sendline(payload) # Drop into an interactive shell to interact with the program p.interactive()

In this example, we create a payload that consists of 16 bytes of 'A's followed by the address of our own code. We then send this payload to the vulnerable program using a local process. Once the payload is executed, the program will return to our code instead of returning to the original function.

Tools for Binary Exploitation

There are many tools available for binary exploitation, each with its own strengths and weaknesses. Some popular tools for binary exploitation include:

1. gdb - A powerful debugger that allows you to step through

To use gdb, you can start by running the program with gdb:

$ gdb ./program

Once the program is loaded, you can set breakpoints at specific locations in the code using the `break` command. For example, to set a breakpoint at the beginning of the main function, you can use:
 

(gdb) break main

You can then run the program using the `run` command. When the program hits a breakpoint, gdb will stop execution and allow you to inspect the program's state using commands like `print` to print the value of a variable, `x` to examine the contents of memory at a specific address, and `step` or `next` to step through the program's execution.

2. objdump - A tool for examining the contents of compiled binary files.

To use objdump, you can run it on a compiled binary file:

$ objdump -d program

This will disassemble the binary file and display the assembly code for each function. You can then use this information to identify potential vulnerabilities in the code.

3. pwntools - A Python library for interacting with binary programs and performing binary exploitation.

Pwntools provides a convenient interface for interacting with binary programs, including starting local processes, sending input to the process, and receiving output from the process. It also provides tools for generating payloads and exploiting vulnerabilities in the program.

To use pwntools, you can start by importing the library:

from pwn import *

You can then use pwntools to start a local process, send input to the process, and interact with the process:

# Start a local process p = process('./program') # Send input to the process p.sendline('input') # Receive output from the process output = p.recvline() # Interact with the process p.interactive()

Conclusion

Binary exploitation is a powerful technique for identifying and exploiting vulnerabilities in software applications. By understanding the basics of how programs execute and how vulnerabilities can be exploited, penetration testers can identify weaknesses in a system's security and help organizations improve their overall security posture. With the right tools and knowledge, binary exploitation can be an effective tool for any pen tester's toolkit.
