MassVulScan

🔍 A fast network scanning tool to detect open ports and security vulnerabilities

Tag Issues Last Commit Bash software License Stars

🌟 Overview

MassVulScan is a high-performance network scanning tool for pentesters (HackTheBox / HTB compatible) and system/network administrators looking to identify open ports and potential vulnerabilities on their internal/external networks. Built on powerful tools like masscan and nmap, it combines speed and accuracy to scan large-scale networks efficiently.

🎯 Features

  • Fast Port Scanning: Built on masscan for quick open-port detection.
  • Vulnerability Detection: Uses nmap scripts for detailed service analysis.
  • Optimized Scans: Intelligent subnet filtering to avoid duplicates.
  • Platform Compatibility: Runs on Linux, Debian OS family only.
  • Power of Bash: Simplicity meets performance

📋 Changelog

Changelog

Last update

1.9.4 (2024-10-24)

Implemented enhancements or changes:

  • Detect and deduplicate CIDR subnets to avoid multiple scan E.g.: 10.10.18.0/28 is contained within 10.10.18.0/24 so we only keep 10.10.18.0/24 (the larger one)

Fixed bugs:

  • no reported issue by the community

📦 Installation

Ensure the following prerequisites are installed:

  • masscan (version >= 1.0.5)
  • nmap (version >= 7.60)
  • NSE vulners script
  • xsltproc package
# Clone the repository
git clone https://github.com/choupit0/MassVulScan.git

# Go to the project directory
cd MassVulScan

# Install dependencies (root or sudo)
./sources/installation.sh

Additional parameters

Parameter Description
--auto-installation-latest compilation of the latest versions of nmap and masscan -> ~5 minutes (default)
--auto-installation-apt speedest but not the last versions -> ~1 minute

Note about APT installation Warning, I detected an error with the APT version. There is a mistake of upstream. The Masscan version 1.0.5 tag points to a commit that still contains 1.0.4 as version. But this is the correct code for the 1.0.5 version. robertdavidgraham/masscan#566 (comment) (Thank you to https://github.com/rhertzog)

🛠️ How MassVulScan Works

MassVulScan follows a series of streamlined steps to identify active hosts, open ports, and potential vulnerabilities across your network:

  1. Quick Host Discovery (optional): Uses nmap to identify online hosts efficiently.
  2. Rapid Port Scanning: For each host, masscan performs an ultra-fast scan to detect open TCP/UDP ports.
  3. Data Organization: Results are sorted to compile all detected ports and protocols by host. The organized data can be saved for later analysis (optional).
  4. Service and Vulnerability Detection: Runs multiple parallel sessions (nmap + vulners.nse) to detect services and vulnerabilities, one session per host.
  5. Report Generation:
    • HTML Report: Contains detailed information on each host, including vulnerabilities, with a clean and accessible layout.
    • TXT Report: Focuses on potentially vulnerable hosts for quick reference.

The HTML report uses a Bootstrap stylesheet (nmap-bootstrap-xsl) for enhanced readability and a user-friendly format.

🚀 Usage

File-based scanning mode:

targets.txt containing a list of networks, IPs and/or hostnames to scan.

sudo ./MassVulScan.sh -f targets.txt

exclude.txt containing including IPv4 addresses (CIDR format compatible) to NOT scan.

sudo ./MassVulScan.sh -f targets.txt -x exclude.txt

Full option list:

sudo ./MassVulScan.sh -h

⚙️ Required options

Option Description
-f File with IPs (CIDR format compatible) or hostnames to scan, one by line

⚙️ Optional options

Option Description
-x Exclude these IPs (CIDR format compatible), one by line (e.g. gateways from your providers)
-i Interactive mode: ports to scan, rate level and NSE script to use (e.g. vulners --script-args mincvss=5)
-a Scan all ports (TCP + UDP) at 1.5K pkts/sec with NSE vulners script
-c Perform a pre-scanning to identify online hosts and scan only them
-r Generate a TXT file including IPs scanned with open ports and protocols
-n Quick mode without full Nmap scan to detect the hosts with open ports (no HTML report)
-h Show help
-V Show MassVulScan version

By default the script will scan only the first 1000 TCP/UDP ports among the most common ports. You can find the list here: /usr/local/share/nmap/nmap-services. Similarly, the rate or number of packets per second is set to 1500 by default.

Note that the script will detect if you have multiple network interfaces. This is important for Masscan, which will always used the interface that has the default route. You will be asked to choose one (no problem with Nmap).

The script is also compatible with Nmap's categories (https://nmap.org/book/nse-usage.html#nse-categories) to search for specific vulnerabilities (the better known as ms17-010, EternalBlue) in addition to the CVEs identified from vulners.com.

🐞 Known issues

No known issues.

✅ TODO

Improve the pre-scanning phase to identify online hosts (fping).

Manage better multiple IP addresses on one network interface.

Improve process of installation (install what is strictly necessary, comparison of versions).

Improve the parsing of hosts file to detect duplicate networks, Ex: 10.10.18.0/24 and 10.10.18.0/28, and avoid duplicate scan.
