Port 5357 is more than just an obscure port – it’s a potential entry point for unauthenticated info leaks, NTLM relaying, and legacy RCE. While not as juicy as 445, it’s often overlooked, making it a reliable target for lateral movement during internal penetration tests. port 5357 hacktricks

A typical result for an open port 5357 is:

Understanding Port 5357: Security Insights and Enumeration Port 5357 is commonly utilized by Microsoft Windows operating systems for the Web Services for Devices (WSD) API. This service allows devices like printers, scanners, and file shares to discover each other automatically over a local network. In a penetration testing or red teaming engagement, finding this port open provides a valuable opportunity to gather intelligence about the target machine.

Poorly secured WSD services can expose web-based admin pages for printers or scanners, potentially allowing attackers to view or submit print jobs. the internal network to identify specific Windows versions

Port 5357 is not inherently malicious, but its presence provides several opportunities for an attacker to gain information about the network. A. Information Disclosure (Network Mapping) WSD can disclose sensitive device information, including:
