OpenSSH Pre-Auth Double Free CVE-2023-25136 POC

This repository contains a Proof of Concept (POC) script to check for the OpenSSH Pre-Auth Double Free vulnerability (CVE-2023-25136) using the Paramiko library in Python.

Prerequisites

Before running this POC script, you need to make sure you have the following dependencies installed:

• Python 3.x
• Paramiko library
• termcolor library
• argparse library

You can install all of the requirements using pip:

pip install -r requirements.txt

Usage

To check for the vulnerability on a single IP address, run the script with the -i option followed by the IP address:

python CVE-2023-25136.py -i 192.168.1.1

To check for the vulnerability on multiple IP addresses, create a file containing a list of IP addresses (one per line) and run the script with the -f option followed by the file name:

python CVE-2023-25136.py -f ip_list.txt

Output

The script will output whether each IP address is vulnerable or not. If an IP address is vulnerable, it will be printed in green text, and if it is not vulnerable, it will be printed in red text.
