5357/tcp open http Microsoft HTTPAPI httpd 2.0 (SSDP/UPnP) |_http-title: Service Unavailable Use code with caution.

: Because it exposes an HTTP server by default, attackers can query it to gather system data. 2. Enumeration and Information Gathering

Primarily Windows Vista and later, including Windows 10, 11, and Windows Server. How WSDAPI Works port 5357 hacktricks

Port 5357 is commonly utilized by Microsoft Windows for the Web Services on Devices (WSD) API. This service allows devices like printers, scanners, and file shares to be discovered and managed automatically over a local network. While highly convenient for enterprise and home networking, exposing this port can provide attackers with valuable reconnaissance data and potential vectors for lateral movement.

If the WSD endpoint belongs to a , the host might be vulnerable to the PrintNightmare chain:

Your first step should always be an Nmap scan to identify the service version and running scripts. nmap -p 5357 -sV -sC Use code with caution. Port 5357 is typically used for the service,

If you manage to exploit the vulnerable service, you can deploy standard post-exploitation toolkits like for credential dumping, PowerShell Empire for further enumeration, or Cobalt Strike for long-term persistence.

Port 5357 rarely suffers from direct remote code execution vulnerabilities, but it is an excellent source for infrastructure data harvesting. Hostname and Domain Leakage

Apply Microsoft updates, particularly those addressing WSDAPI vulnerabilities. 5. Investigation Commands To check if Port 5357 is open on a Windows system: netstat -anb | find "5357" Use code with caution. Copied to clipboard If the port is listening, it often shows:

The initial scan revealed the target on the local network with TCP port 5357 open, tagged by nmap as the wsdapi service. Having identified this service, the next step was to inspect it manually.
