Hacktricks Link — Port 5357

The primary risk associated with an exposed Port 5357 is information leakage. By querying the WSD endpoints, an unauthenticated attacker on the network can often discover: : The NetBIOS or DNS hostname of the target.

The WS-Discovery protocol exposes machine names, unique UUIDs, and hardware capabilities to the local network.

An attacker inside a compromised network can scan for port 5357 across the subnet. Because it indicates a Windows environment or network-connected office hardware, it helps map out where the high-value workstation and printing infrastructure resides. 5. Defensive Hardening and Mitigation port 5357 hacktricks

The process involves:

5357 (HTTP), 5358 (HTTPS), and 3702 (UDP - multicast for discovery). PentestPad 2. HackTricks & Pentesting Context: Common Risks The primary risk associated with an exposed Port

Information gathering is the first step when encountering port 5357. Nmap Scanning

Historically, the most severe flaw targeting this architecture was Microsoft Security Bulletin MS09-063 . An attacker inside a compromised network can scan

Port 5357 should typically only be open on local, trusted networks.

Vulnerability in Web Services on Devices (WSD) API - Microsoft

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

If you encounter Port 5357 during a scan, consider the following: Identify the Process : Use commands like netstat -anb | find "5357"
