Cisco SD-WAN Exposure Scanner (CVE-2026-20127)

A specialized passive fingerprinting tool designed to identify internet-facing Cisco SD-WAN (vManage / Viptela) instances. This tool helps security researchers and system administrators manage their external attack surface by detecting potentially exposed management interfaces and NETCONF ports.

🚀 Features

  • Multi-Port Analysis: Scans common SD-WAN ports including 22 (SSH), 443 (HTTPS), and 830 (NETCONF).
  • HTTP/HTTPS Fingerprinting: Detects "vManage", "Viptela", and "Cisco SD-WAN" in page titles and Server headers.
  • SSL/TLS Inspection: Analyzes certificate Common Names (CN) for SD-WAN identifiers.
  • Service Banner Grabbing: Utilizes nmap for advanced service versioning and banner extraction.
  • Asynchronous Execution: High-performance scanning using asyncio and aiohttp for rapid target processing.
  • Network Expansion: Built-in support for CIDR range expansion and file-based target lists.
  • Structured Output: Generates detailed JSON reports for integration with other security tools.

📋 Prerequisites

  • Python: 3.7 or higher
  • Nmap: Must be installed on the host system and available in the PATH.
  • Python Libraries:
    • requests
    • python-nmap
    • ipaddress
    • asyncio
    • aiohttp

🛠️ Installation

  1. Install Nmap:

    • Windows: Nmap Download
    • Linux: sudo apt install nmap

  2. Install Python Dependencies:

    root@kitploit:~
    pip install requests python-nmap ipaddress asyncio aiohttp

📖 Usage

The scanner supports three main targeting modes:

Single Target

root@kitploit:~
python sdwan.py --target 203.0.113.50

CIDR Range

root@kitploit:~
python sdwan.py --cidr 203.0.113.0/24 --ports 443,830 --timeout 3

File-based Targets

root@kitploit:~
python sdwan.py --file targets.txt

Command Line Arguments

ArgumentDescriptionDefault
--targetSingle IP address or hostname to scan.None
--cidrCIDR network range (e.g., 192.168.1.0/24).None
--filePath to a file containing one IP/CIDR per line.None
--portsComma-separated list of ports to scan.22, 443, 830
--timeoutConnection timeout in seconds.4.0
--outputFilename for the JSON output report.sdwan_scan.json

📊 Output Example

The tool generates a JSON report containing detailed findings for each target:

root@kitploit:~
[
  {
    "ip": "203.0.113.50",
    "timestamp": "2026-03-08T09:05:13.123Z",
    "open_ports": [443, 830],
    "indicators": [
      "Title match: vmanage",
      "Cert CN: vmanage.local",
      "Port 830 banner: NETCONF over SSH"
    ],
    "confidence": "high",
    "status": "POTENTIAL SD-WAN EXPOSURE"
  }
]
