WSD can leak metadata including hostnames, device models (e.g., printer types), network paths, and unique device identifiers (GUIDs).
To advance your network penetration testing capabilities, you can explore related service exploitation. Let me know if you would like to look into via LLMNR/NBT-NS spoofing or if you want to examine Active Directory lateral movement techniques. Share public link
But the HackTricks page had warned about a darker possibility. Sometimes, this port was tied to the "Network Discovery" feature, which utilized the and NBNS protocols. While this was technically a different vector, they often overlapped in misconfigurations. port 5357 hacktricks
For high-security environments, you can disable the "Function Discovery Resource Publication" service. 5. Summary Table Description 5357 TCP WSDAPI Web Services for Devices (HTTP) Info Disclosure, Lateral Movement 3702 UDP WS-Discovery Discovery Mechanism Information Gathering
Potentially intercepting print jobs, which may contain sensitive company documents. 4. Remediation and Mitigation WSD can leak metadata including hostnames, device models (e
While primarily an SMBv3 vulnerability, some research has linked WSD-exposed interfaces to broader exploit chains in similar network discovery contexts. Detection and Mitigation
She crafted a second packet, this time pretending to be a printer looking for a driver share. Share public link But the HackTricks page had
The use of port 5357 for remote management and execution of commands makes it an attractive target for hackers. By exploiting vulnerabilities or misconfigurations associated with this port, attackers can gain unauthorized access to sensitive information, execute malicious code, or even take control of the targeted system.
WS-Discovery responds to SOAP requests. Attackers can craft XML queries to force the system to dump metadata. This metadata often includes computer names, domain details, internal IP addresses, and unique hardware IDs. 3. NTLM Relay Attacks
Port 5357 is primarily associated with Web Services for Devices (WSDAPI)
