Is there a tool that shows the camera serial number when searching for port="37777"?
I don't know any specific utilities, but you can try to get the serial number using the following tool:
Nmap is a popular network scanner that can be used to find cameras through port 37777 and extract information about them.
However, additional script setup will be required to obtain specific information such as the serial number.
To retrieve the serial number of cameras through port 37777 using Nmap, you can use the Nmap Scripting Engine (NSE).
This is a powerful capability that allows automating tasks like obtaining serial numbers from cameras when standard scanning is insufficient.
Example of a custom Nmap script for serial number extraction:
This example shows how to write a script that requests system information from the camera via a CGI request, typical for Dahua cameras using port 37777.
```
local shortport = require "shortport"
local http = require "http"
local stdnse = require "stdnse"
description = [[
Attempts to retrieve the serial number from a Dahua camera on port 37777.
]]
categories = {"discovery", "safe"}
portrule = shortport.port_or_service(37777, "tcp")
action = function(host, port)
local path = "/cgi-bin/magicBox.cgi?action=getSystemInfo"
local response = http.get(host, port, path)
if response and response.status == 200 then
local serial_number = response.body:match("serialNumber=(%w+)")
if serial_number then
return "Serial Number: " .. serial_number
else
return "Serial number not found in response."
end
else
return "No response from the device."
end
end
```
This code is written in Lua and designed for use with Nmap, a popular network scanner.
How to use this script:
1. Save this code in a file with the .nse extension, for example, dahua-serial.nse.
2. Run Nmap, specifying this script and the IP address of your camera:
```
nmap -p 37777 --script=dahua-serial.nse <IP address or IP range>
```
What this script does:
- Sends an HTTP request to the camera at the path /cgi-bin/magicBox.cgi?action=getSystemInfo.
This is an API request that many Dahua cameras support for retrieving system information.
- Extracts the serial number if the camera returns it in the response (in the format serialNumber=XXXXXXX).
- Outputs the serial number to the Nmap console if found. If not, returns the message "Serial number not found in response."
How it works:
- Cameras using port 37777 (such as Dahua) may respond to HTTP requests via their API.
This script uses an HTTP request to the standard API to retrieve system information, including the serial number, if the camera provides such information.
- The script runs through Nmap, allowing you to scan the network and gather information about devices simultaneously.
If the camera does not respond to such a request, you may need to modify the script or try other query paths, depending on the camera's documentation or protocol used.
