As the first port in the dynamic/private range (49152-65535), this port is commonly used by applications that utilize a dynamic/random/configurable port.
Many embedded Linux based systems (i.e. home routers, remote management devices, IP cameras) have UPnP enabled, broadcasting their kernel version and hardware architecture over port 49152.
Some P2P torernt clients often use this port: uTorrent, Azureus/Vuze, etc.
Older IPMI firmware versions reveal cleartext login credentials over UDP port 49152.
Apple AirPlay dynamic mirroring TCP port.
YotaPhone 2 opens port 49152.
Apple Xsan Filesystem Access uses the dynamic/private range 49152-65535.
Xsan (Apple's storage area network, or clustered filesystem for macOS) uses these ports:
311 TCP - Xsan secure server administration (server app, xsan server admin, workgroup manager, server monitor)
312 TCP - Xsan administration
626 UDP - server serial number registration (Xsan, Mac OS X Server v10.3 – v10.6)
49152-65535 TCP - Xsan Filesystem Access
Microsoft Lync server uses these ports:
444, 445, 448, 881, 5041, 5060 - 5087, 8404 TCP
80, 135, 443, 4443, 8060, 8061, 8080 TCP - standard ports and HTTP(s) traffic
1434 UDP - SQL
49152-57500 TCP/UDP - media ports
The AT&T U-verse 9.2.2h0d83 firmware for the Arris NVG589 and NVG599 devices, when IP Passthrough mode is not used, configures an unauthenticated proxy service on WAN TCP port 49152, which allows remote attackers to establish arbitrary TCP connections to intranet hosts by sending \x2a\xce\x01 followed by other predictable values.

The LAN-side Web-Configuration Interface has Stack-based Buffer Overflow vulnerability in the D-Link Wi-Fi router firmware DIR-890L DIR890LA1_FW107b09.bin and previous versions. The function created at 0x17958 of /htdocs/cgibin will call sprintf without checking the length of strings in parameters given by HTTP header and can be controlled by users easily. The attackers can exploit the vulnerability to carry out arbitrary code by means of sending a specially constructed payload to port 49152.

SANS Internet Storm Center: port 49152
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.
