Port 5357 Hacktricks

Port 5357 is an interesting target for exploration during penetration tests and vulnerability assessments. Understanding the services running on this port and potential vulnerabilities can help you better assess and secure your systems. For more information, be sure to check out the HackTricks resources listed above.

Attackers can craft valid WS-Discovery SOAP requests to force the service to dump device metadata. This data often includes: Computer hostnames Unique Device UUIDs Exact Windows build versions

Port 5357 - Web Services for Devices (WSD) Pentesting Guide Port 5357 is commonly used by the feature in Microsoft Windows environments . It hosts the Web Services for Devices (WSD) protocol over HTTP. While often overlooked during external assessments, misconfigured or unpatched WSD endpoints can serve as a critical vector for reconnaissance, credential harvesting, and lateral movement during internal network pentests. 1. Protocol Fundamentals port 5357 hacktricks

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

Many devices (and even Windows hosts with sharing enabled) expose metadata without authentication. Port 5357 is an interesting target for exploration

5357/tcp open http Microsoft HTTPAPI httpd 2.0 |_http-title: Service Unavailable |_http-server-header: Microsoft-HTTPAPI/2.0

If the endpoint requires NTLM authentication (e.g., for GetPrinterData action), you can trigger an authentication attempt: Attackers can craft valid WS-Discovery SOAP requests to

curl -v http:// :5357/ -H "Host: stuff" -H "Range: bytes=0-18446744073709551615" Use code with caution.
