Port 5357 Hacktricks

Web Services Dynamic Discovery (WS-Discovery) is a multicast protocol used to locate services on a local network. It operates over HTTP (TCP port 5357) and HTTPS (TCP port 5358).

:Since 5357 is the HTTP unicast part of WSD, it is often paired with UDP port 3702 , which handles multicast discovery. Pentesting the UDP discovery service can often provide more detailed device information than the TCP port alone. Vulnerability Context

Because Port 5357 hosts an HTTP server, standard web enumeration tools and network scanners can extract significant information about the host. Network Scanning (Nmap)

user wants a long article about "port 5357 hacktricks". This suggests they want an article similar to those on the HackTricks platform, covering security assessment and exploitation techniques for port 5357. I need to gather information from HackTricks and other sources. I'll follow the search plan provided in the hints. search results for "port 5357 hacktricks" didn't show any direct HackTricks article. The other searches didn't yield specific HackTricks content either. I need to gather more information from other sources. I'll open the relevant results I found. have gathered information from various sources. Now I need to structure a comprehensive article. The outline will include: an introduction to port 5357, its relation to HackTricks, enumeration techniques, vulnerabilities, exploitation methods, post-exploitation, persistence, mitigation, responsible disclosure, checklists, references, and a conclusion. I will cite the sources appropriately. is a detailed article on performing a security assessment of port 5357 from a penetration tester's perspective, inspired by the style and depth found in the platform.

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 Web Services Dynamic Discovery (WS-Discovery) is a multicast

A standard version scan will often reveal the underlying HTTP server. nmap -sV -p 5357 Use code with caution. Copied to clipboard

Port 5357/tcp is one of those network services that often flies under the radar, yet for penetration testers, it can represent a gateway to deeper discovery and, in some cases, system compromise. While not as notorious as 445/SMB or 3389/RDP , understanding the service behind this port is a valuable asset in any security assessment.

Block port 5357 at the perimeter firewall. This port should never be exposed to the public internet. Pentesting the UDP discovery service can often provide

Get-CimInstance -Namespace root\cimv2 -ClassName Win32_PnPEntity | Where-Object $_.Caption -match "WSD" Use code with caution. 5. Mitigation and Hardening

Port 5357 is a prime example of a service that is often misunderstood. It is exploitable, but the attack surface is primarily limited to the local network. While exploiting this port from the internet is highly unlikely, its presence on a local network poses a significant risk. For penetration testers, it represents a potential initial foothold for lateral movement within an organization. For system administrators, it is a port that should be strictly filtered or the service disabled unless explicitly needed for a legitimate function.

You can also monitor the network for WSD activity. Use tcpdump or Wireshark to capture multicast traffic on UDP port 3702 and HTTP traffic on TCP port `5357. This can help you identify all devices on the network that are broadcasting their presence and services.
