Port 5357 Hacktricks -

You can also monitor the network for WSD activity. Use tcpdump or Wireshark to capture multicast traffic on UDP port 3702 and HTTP traffic on TCP port `5357. This can help you identify all devices on the network that are broadcasting their presence and services.

Because the service runs over HTTP, you can query it using standard web tools. curl -i http:// :5357/ Use code with caution. Checking Common Paths

You can utilize native Windows PowerShell commands to query WSD infrastructure directly without uploading external binaries: powershell

SpoolSample.exe TARGET-50 AttackerPC

5357/tcp open http Microsoft HTTPAPI httpd 2.0 (SSDP/UPnP) port 5357 hacktricks

Configure Windows Defender Firewall to allow traffic on TCP port 5357 exclusively from the local subnet ( LocalSubnet ). Keep Systems Updated

It works in conjunction with , where UDP acts as the discovery mechanism, and TCP 5357 serves the actual device metadata over HTTP. 2. Reconnaissance and Enumeration

If device discovery features are not required on a server or workstation, disable the underlying service: Open services.msc .

Port 5357 should never be open to the internet and should ideally be filtered even on public local networks. You can also monitor the network for WSD activity

Understanding Port 5357: Security Analysis and Exploitation Guide

Allows Windows to automatically discover and communicate with local network devices like printers and scanners.

This is the most common use case. Attackers can query the WSD interface to leak device hostnames, printer names, network paths, and device metadata useful for fingerprinting a target .

: Attempt to browse the port via HTTP. While it may not serve a traditional webpage, it may respond with XML data or SOAP responses that reveal device identity. Network Context Because the service runs over HTTP, you can

Identifying machine roles (e.g., PRINTER-FINANCE ).
