Wsdiscovery - WS-Discovery Protocol Scanner

You are helping the user discover and enumerate devices using the WS-Discovery protocol (commonly used by ONVIF cameras and IoT devices) using the wsdiscovery tool.

Tool Overview

Wsdiscovery implements the WS-Discovery protocol to discover network devices that support this standard. It's particularly useful for finding ONVIF cameras, network video recorders (NVRs), and other IoT devices that advertise themselves via WS-Discovery.

Instructions

When the user asks to discover ONVIF devices, find network cameras, or scan for WS-Discovery devices:

  1. Understand the target:

    • Ask for the target hostname or IP address
    • Determine if they want verbose output (full XML responses)
    • Decide on output format
  2. Execute the scan:

    • Use the wsdiscovery command from the iothackbot bin directory
    • Basic usage: wsdiscovery <hostname_or_ip>
    • For verbose output: wsdiscovery <hostname_or_ip> -v
    • For JSON output: wsdiscovery <hostname_or_ip> --format json
  3. Output formats:

    • --format text (default): Human-readable colored output with device details
    • --format json: Machine-readable JSON
    • --format quiet: Minimal output

What It Discovers

The tool extracts and displays:

  • IP addresses and ports
  • Endpoint references (device UUIDs)
  • Device types
  • Manufacturer information
  • Device names and models
  • Hardware versions
  • Serial numbers
  • Firmware versions
  • Location information
  • Service endpoints (XAddrs) - URLs for device management
  • Metadata versions

Examples

Discover devices on a specific host:

bash
wsdiscovery 192.168.1.100

Discover with full XML responses:

bash
wsdiscovery 192.168.1.100 -v

Output device information as JSON:

bash
wsdiscovery 192.168.1.100 --format json

Scan network broadcast address to find all devices:

bash
wsdiscovery 239.255.255.250

Important Notes

  • WS-Discovery uses multicast/broadcast discovery
  • Devices must support the WS-Discovery protocol to be found
  • Common with ONVIF cameras, printers, and network media devices
  • Service endpoints (XAddrs) can be used with onvifscan for further testing
  • The tool parses ONVIF-specific scope information when available
