Port 5357 Hacktricks ^new^ -

Securing port 5357 requires restricting access and ensuring the operating system is fully updated.

is commonly used by:

Port 5357 is a TCP port that is commonly associated with the Windows Remote Management (WinRM) service. WinRM is a Microsoft protocol that enables remote management of Windows systems, allowing administrators to execute commands, access event logs, and perform other management tasks remotely. While WinRM is a legitimate technology, its openness and lack of robust security measures have made it a popular target for attackers.

: By interacting with WSD, an attacker might identify other vulnerable devices on the subnet that wouldn't otherwise be visible through standard scanning. Practical Assessment Steps port 5357 hacktricks

Why port 5357 matters

curl -I http://<target_ip>:5357

May indicate the service is disabled or strictly bound to local interfaces. 3. Attack Vectors & Exploitation Information Disclosure via SOAP Envelopes Securing port 5357 requires restricting access and ensuring

: Windows uses it to enable seamless, configuration-free network discovery.

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).

Printer names, hostnames, and network paths. While WinRM is a legitimate technology, its openness

If the server responds with Requested Range Not Satisfiable , the system may be vulnerable or sensitive to the exploit payload. C. SSRF and Relay Attacks

To help provide more specific guidance, are you looking to this port in a lab environment or remediate it on a live network? You can also specify the target operating system version to narrow down applicable vulnerabilities. Share public link

While direct RCE via HTTPAPI is a major concern, port 5357 also facilitates other attack methods.
