Vuln_yab - Python-Based Vulnerability Scanner:

Welcome to Vulnyab — a powerful and educational open-source vulnerability scanner built in Python.

This repository includes two versions of the scanner:

1. Basic Scanner – Great for learning port scanning fundamentals.
2. Advanced Scanner – A comprehensive vulnerability assessment tool that integrates Nmap, CVE lookups, PDF reporting, and risk scoring.

Project Overview

Vulnyab is built for learners, ethical hackers, and cybersecurity enthusiasts. It starts with the fundamentals and scales to a semi-professional tool that demonstrates:

• Port scanning
• Service fingerprinting
• Vulnerability detection (CVE lookup)
• Report generation

---

Basic Scanner

Description

A simple port scanner using Python’s built-in socket module. It scans a given range of ports and prints all open ports on the target.

Ideal for beginners who want to:

• Understand TCP handshakes
• Learn how port scanners work from scratch

Usage

cd basic/
python basic_scanner.py

• Enter the target IP/domain.
• Provide the port range (start & end).
• See the list of open ports.

Requirements

• Python 3.x (tested with Python 3.6+)
• No external libraries needed

Advanced Scanner

Advanced Description

The advanced version elevates the scanner by using:

• nmap for detailed port & service scanning
• Public CVE databases for vulnerability detection
• fpdf for professional report generation

This tool suits intermediate to advanced users and demonstrates real-world vulnerability scanning practices.

Features

• 🛠 Service & version detection via Nmap

• Automatic CVE lookup (via Vulners API)

• Generates PDF reports with:

• Scan summary

• Detected services & vulnerabilities

• OS info, uptime, and traceroute

• CVSS-based risk scoring with color-coded severity

• Output in both terminal and PDF format

Setup & Requirements

Install the dependencies:

pip install nmap requests fpdf

Install Nmap:

• Linux (Ubuntu/Debian):

  sudo apt-get install nmap

• Windows: Download from https://nmap.org/download.html

Ensure the fonts/ folder exists in advanced/ directory:

• Contains required fonts for PDF: DejaVuSans.ttf, DejaVuSans-Bold.ttf, DejaVuSans-Oblique.ttf

Advanced Usage

cd advanced/
python scanner.py

• Enter target IP/domain
• Optional: Generate a PDF report

Scan results and CVEs are displayed in the terminal and saved to a PDF report.
