Enables automatic discovery of network-connected devices (printers, scanners, cameras) over HTTP, allowing them to communicate on local networks without needing central servers or manual configuration.
addressed a critical vulnerability where specially crafted headers could lead to remote code execution. Lateral Movement
WSDAPI can leak significant metadata that aids in lateral movement: and computer names. Device metadata such as printer models or scanner types. Network paths and file share locations. Known Vulnerabilities and Exploitation MS09-063: Memory Corruption (CVE-2009-2512) port 5357 hacktricks
: The service can leak metadata such as device hostnames, manufacturer details, and network paths. Attackers use this for fingerprinting
"Recommendation: Block Port 5357/tcp on the perimeter firewall immediately. The exposed WS-Discovery service allowed for the enumeration of the primary Domain Controller hostname ('LEDGER-DC01') and internal network topology without authentication." Device metadata such as printer models or scanner types
Step 1: Open the Control Panel Step 2: Click on Windows Firewall/ Windows Defender firewall Step 3: Navigate to advanced settings. ManageEngine Penetration Testing: Re: Port 5357 -- Vista SP1 ???
The discovery process usually begins with a multicast message over . Once a device is discovered and a handshake is completed, further communication and data exchange move to TCP port 5357 (HTTP) or TCP port 5358 (HTTPS). and network paths.
One of the most critical vulnerabilities associated with WSDAPI is a .
