A stack-based buffer overflow vulnerability. Attackers could send a crafted WS-Discovery message with an overly long "MIME-Version" string to execute arbitrary code with service-level privileges.

Port 5357: Deep Dive into WSDAPI and Network Discovery In modern Windows environments, port 5357 (TCP) is a frequently encountered service that often appears during internal network scans. While it is a standard component for device discovery, it can provide valuable information for penetration testers or present a security risk if mismanaged. What is Port 5357?
