Port(s) Protocol Service Details Source
13838 tcp applications hydra.exe in HP SAN/iQ before 9.5 on the HP Virtual SAN Appliance has a hardcoded password of L0CAlu53R for the global$agent account, which allows remote attackers to obtain access to a management service via a login: request to TCP port 13838.
References: [CVE-2012-4362]

HP LeftHand Virtual SAN Appliance is vulnerable to a stack-based buffer overflow in the LHNSessionManager component of the hydra service. By sending an overly long username to the hydra service listening on TCP port 13838, a remote attacker could overflow a buffer and execute arbitrary code on the system with root privileges.

TCP ports use the Transmission Control Protocol. TCP is the most commonly used protocol on the Internet and any TCP/IP network. Whereas the IP protocol deals only with packets, 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, a communications protocol for the Internet network, transport, and session layers. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) and makes possible 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, 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.
