Vulnerabilities: Check CERT advisories CA-2002-22 - multiple vulnerabilities, CA-2003-04 MS SQL Server Worm. The Gaobot family of worms also exploit this port.
See also: Microsoft Security Bulletin [MS02-061].
Digispid.B.Worm [Symantec-2002-052108-5430-99] (2002.05.21) - worm that spreads to computers running MS SQL server and have blank SQL admin password. Uses port 1433/tcp.
W32.Kelvir.R [Symantec-2005-041214-1218-99] (2005.04.12) - worm that spreads through MSN messenger and drops a variant of W32.Spybot.Worm. It spreads using several known MS vulnerabilities, including MS security Bulletin [MS02-061] Microsoft SQL Server 2000 or MSDE 2000 audit using port 1434/udp.
Buffer overflow in a component of SQL-DMO for Microsoft Data Access Components (MDAC) 2.5 through 2.7 allows remote attackers to execute arbitrary code via a long response to a broadcast request to UDP port 1434.
References: [CVE-2003-0353] [BID-8455]
A vulnerability has been identified in SIMATIC IT UADM (All versions < V1.3). An authenticated remote attacker with network access to port 1434/tcp of SIMATIC IT UADM could potentially recover a password that can be used to gain read and write access to the related TeamCenter station. The security vulnerability could be exploited only if the attacker is authenticated. No user interaction is required to exploit this security vulnerability. Successful exploitation of the security vulnerability compromises the confidentiality of the targeted system. At the time of advisory publication no public exploitation of this security vulnerability was known.

SANS ISC: port 1434
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.
