Cisco IOS is vulnerable to a denial of service, caused by an error within the Common Industrial Protocol (CIP) feature when processing malicious packets. By sending specially-crafted IPv4 packets destined to TCP port 44818, a remote attacker could exploit this vulnerability to cause the device to reload.
References: [CVE-2015-0649], [XFDB-101804]
Rockwell Automation ControlLogix is vulnerable to a denial of service, caused by the improper validation of input being sent to the buffer. By sending a specially-crafted CIP message to TCP and UDP ports 2222 and 44818, a remote attacker could exploit this vulnerability to cause the CPU to stop logic execution and enter a denial of service.
References: [XFDB-81235]
Rockwell Automation RSLinx Classic Versions 4.00.01 and prior. This vulnerability may allow a remote threat actor to intentionally send a malformed CIP packet to Port 44818, causing the software application to stop responding and crash. This vulnerability also has the potential to exploit a buffer overflow condition, which may allow the threat actor to remotely execute arbitrary code.
References: [CVE-2018-14829]
Rockwell Automation RSLinx Classic Versions 4.00.01 and prior. A remote, unauthenticated threat actor may intentionally send specially crafted Ethernet/IP packets to Port 44818, causing the software application to stop responding and crash. The user must restart the software to regain functionality.
References: [CVE-2018-14827]
Rockwell Automation RSLinx Classic Versions 4.00.01 and prior. This vulnerability may allow a remote, unauthenticated threat actor to intentionally send a malformed CIP packet to Port 44818, causing the RSLinx Classic application to terminate. The user will need to manually restart the software to regain functionality.
References: [CVE-2018-14821]
Tec4Data SmartCooler is vulnerable to a denial of service, caused by missing authentication for a critical function. By sending a specially crafted CIP packet to Port 44818, a remote attacker could exploit this vulnerability to cause a denial of service.

SANS Internet Storm Center: port 44818
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.
