ACHUX21/checker-CVE-2024-6387

OpenSSH Vulnerability Checker

Overview

This script scans a list of target IP addresses or ranges to determine if they are running vulnerable To CVE-2024-6387.

Features

• Scans IP addresses, domain names, file paths containing IP addresses, or CIDR network ranges.
• Checks a specified port (default: 22) for OpenSSH service.
• Handles multiple targets concurrently using threading for efficient scanning.
• Reports non-vulnerable, vulnerable, and closed ports.
• Supports exclusion of specific OpenSSH versions known to be patched or not vulnerable.

Requirements

• Python 3.x
• argparse module for command-line argument parsing.
• ipaddress module for handling IP addresses and CIDR notation.

Usage

Command Line Options

usage: openssh_checker.py [-h] [--port PORT] [-t TIMEOUT] [-l LIST] targets [targets ...]

Check if servers are running a vulnerable version of OpenSSH.

positional arguments:
  targets               IP addresses, domain names, file paths containing IP addresses, or CIDR network ranges.

optional arguments:
  -h, --help            show this help message and exit
  --port PORT           Port number to check (default: 22).
  -t TIMEOUT, --timeout TIMEOUT
                        Connection timeout in seconds (default: 1 second).
  -l LIST, --list LIST  File containing a list of IP addresses to check.

Examples

1. Check a single IP address:

   python3 openssh_checker.py 192.168.1.1

2. Check multiple IP addresses from a file:

   python3 openssh_checker.py -l ip_list.txt

3. Check a CIDR range:

   python3 openssh_checker.py 192.168.1.0/24

Output

The script outputs detailed information about each target:

• Servers not vulnerable to OpenSSH exploits.
• Servers likely vulnerable to OpenSSH exploits.
• Servers with closed SSH ports.
• Total number of targets scanned.

Notes

• Ensure that you have appropriate permissions to scan the target hosts.
• Use responsibly and only on systems you are authorized to test.
