Some potential vulnerabilities associated with Port 5357 include:
ntlmrelayx.py -tf targets.txt -smb2support
When assessing port 5357, the primary risk is information disclosure. By querying this port, an attacker can extract metadata about the target system without authentication. Tools such as ntbscan or custom scripts utilizing the Python impacket library can send a probe to the port and receive a response containing the computer name, workgroup, and operating system version. This is critical intelligence for an attacker; knowing the exact OS version allows them to tailor exploits specifically for that environment, bypassing generic defenses. The enumeration of this port aligns with the HackTricks philosophy of "trust but verify"—assuming a network is secure until an open port reveals that a machine is unnecessarily broadcasting its fingerprint. port 5357 hacktricks
Port 5357 is a UDP (User Datagram Protocol) port used by the Windows operating system for various purposes, including:
This forces TARGET-50 (WSD-enabled printer server) to authenticate to your machine on SMB. This is critical intelligence for an attacker; knowing
Regularly update Windows systems to mitigate legacy vulnerabilities like MS09-063.

Port is used by the Web Services for Devices API (WSDAPI) , a Microsoft implementation of the WS-Discovery protocol . It allows Windows systems to automatically discover and communicate with network devices like printers, scanners, and cameras over HTTP. Service Summary Service Name: wsdapi Common Banner: Microsoft-HTTPAPI/2.0 Protocol: HTTP over TCP (Port 5357) or HTTPS (Port 5358).
WS-Discovery endpoints often expose specific UUIDs or long strings as paths. You can utilize tools like ffuf or Gobuster paired with specialized wordlists to find active endpoints under this port, though standard wordlists may yield limited results due to the dynamic nature of WS-Discovery URLs. 3.
