Yahoo Messenger uses this port.
BT Communicator uses ports 5050-5070 (TCP/UDP).
EOSCoreScada.exe in C3-ilex EOScada before 11.0.19.2 allows remote attackers to cause a denial of service (daemon restart) by sending data to TCP port (1) 5050 or (2) 24004.

Saia Burgess Controls (SBC) PCD through 2022-05-06 uses a Broken or Risky Cryptographic Algorithm. According to FSCT-2022-0063, there is a Saia Burgess Controls (SBC) PCD S-Bus weak credential hashing scheme issue. The affected components are characterized as: S-Bus (5050/UDP) authentication. The potential impact is: Authentication bypass. The Saia Burgess Controls (SBC) PCD controllers utilize the S-Bus protocol (5050/UDP) for a variety of engineering purposes. It is possible to configure a password in order to restrict access to sensitive engineering functionality. Authentication is done by using the S-Bus 'write byte' message to a specific address and supplying a hashed version of the password. The hashing algorithm used is based on CRC-16 and as such not cryptographically secure. An insecure hashing algorithm is used. An attacker capable of passively observing traffic can intercept the hashed credentials and trivially find collisions allowing for authentication without having to bruteforce a keyspace defined by the actual strength of the password. This allows the attacker access to sensitive engineering functionality such as uploading/downloading control logic and manipulating controller configuration.

SANS ISC: port 5050
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.
