Port 5357 Hacktricks 🎁 Trending

Domain Controllers rarely need WSD active. If port 5357 is open, the host is likely a workstation, a print server, or a file storage server.

Forcing the target Windows machine to make HTTP calls back to an attacker-controlled server.

Expected Output: Nmap will typically identify the service as microsoft-httpapi or WS-Discovery . The Microsoft-HTTPAPI/2.0 banner confirms a Windows target. Manual Directory Enumeration

This guide provides a detailed overview of Port 5357, methodologies for enumeration, potential vulnerabilities, and remediation strategies based on industry-standard security frameworks like HackTricks. 1. Protocol Overview

This sends a Probe message and lists all advertised devices, their types, scopes, and metadata addresses. port 5357 hacktricks

I can provide more targeted information if you tell me how you want to proceed.

In a typical configuration, WSDAPI uses two primary ports:

git clone https://github.com/ianling/wsdpy cd wsdpy python3 wsdump.py 10.10.10.5

If network discovery is not a business requirement (especially on critical servers), disable the following Windows services: Open services.msc . Locate . Change the Startup type to Disabled and stop the service. Locate Function Discovery Resource Publication . Change the Startup type to Disabled and stop the service. Windows Firewall Configuration Domain Controllers rarely need WSD active

: Sometimes the service can leak the internal hostname or Windows version through the HTTP headers or XML responses.

Because WSD acts as an internal HTTP endpoint tied directly to the Windows HTTP sub-system ( http.sys ), it can occasionally be abused via Server-Side Request Forgery (SSRF) vulnerabilities found in other web applications running on the same host to bypass local firewall restrictions. 4. Post-Exploitation & Lateral Movement

By default, Windows Firewall often allows traffic to this port on private or domain networks, making it a potential target for unauthenticated remote users. Review: Exploitation & Risks

: While less common than port 80 or 443, if the service is misconfigured, it might be leveraged in NTLM relay attacks or for internal network scanning. Common Nmap Command nmap -sV -p 5357 Use code with caution. Copied to clipboard Expected Output: Nmap will typically identify the service

A valid response returns structural data containing machine identifiers, unique UUIDs, active device hardware parameters, and network service addresses. Vulnerability Analysis & Exploitation History

For a penetration tester, any open port represents a potential attack surface, and port 5357 is no different.
