Port 9200 Details

known port assignments and vulnerabilities
threat/application/port search:
Port(s) Protocol Service Details Source
9200 tcp,udp wsp Elasticsearch listens on ports 9200 and 9300 TCP

Starlink gRPC uses ports 9200 and 9201 TCP

Some Lexmark printers open port 9200 TCP/UDP

WapServ Lite, WapServ Pro and WapServ Enterprise are vulnerable to a denial of service. By sending specific byte values over port 9200 or port 9201, a remote attacker can cause the gateway to consume large amounts of memory resources, prevent the gateway from starting, or cause the gateway to crash.
References: [BID-8472], [XFDB-13011]

File Replication Pro could allow a remote attacker to execute arbitrary commands on the system, caused by an error in the ExecCommand function. By viewing configuration.xml, an attacker could exploit this vulnerability to send specially-crafted packet to port 9200 to execute arbitrary commands on the system.

SANS Internet Storm Center: port 9200

Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.

TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.

UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.

When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.
