CiscoWorks Common Services could allow a remote attacker to obtain sensitive information, caused by an error in the Sybase SQL Anywhere database component. By sending a specially-crafted request to UDP port 2638, an attacker could exploit this vulnerability to obtain sensitive information about the engine name and database port.
References: [BID-50376] [CVE-2011-2042] [XFDB-71002]
Sybase Adaptive Server Anywhere Database Engine 6.0.3.2747 and earlier as included with Symantec Ghost 6.5 allows a remote attacker to create a denial of service by sending large (> 45Kb) amounts of data to port 2638.

Symantec Endpoint Protection Manager (SEPM) communicates with the embedded database on this port.
An issue was discovered in Siemens SICAM PAS before 8.00. A factory account with hard-coded passwords is present in the SICAM PAS installations. Attackers might gain privileged access to the database over Port 2638/TCP.

Notes:
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.
