Trojan Horses that use port 5000: Back Door Setup, Blazer5, Bubbel, ICKiller, Ra1d, Sockets des Troie, Socket 23
Trojan.Webus.B [Symantec-2004-100519-0947-99] - DDoS attack trojan, kills antivirus services, 10.05.2004. Uses port 5000/tcp for a DDoS attack.
W32.Mytob.HH@mm [Symantec-2005-071116-2302-99] - a mass-mailing worm with backdoor capabilities. Connects to an IRC server and listens for remote commands on port 26418/tcp. Also opens a backdoor on port 5000/tcp.

UPnP discovery/SSDP, is a service that runs by default on Windows, and there are multiple security vulnerabilities associated with it, especially on older Windows versions. In 2001, Microsoft released 60 updates to Windows related to UPnP vulnerabilities.

Stack-based buffer overflow in Hospira Communication Engine (CE) before 1.2 in LifeCare PCA Infusion System 5.07, Plum A+ Infusion System 13.40, and Plum A+3 Infusion System 13.40 allows remote attackers to cause a denial of service or possibly have unspecified other impact via traffic on TCP port 5000.

OpenLambda 2019-09-10 allows DNS rebinding attacks against the OL server for the REST API on TCP port 5000.
References: [CVE-2019-20329]

Lack of authentication in the network relays used in MEGVII Koala 2.9.1-c3s allows attackers to grant physical access to anyone by sending packet data to UDP port 5000.
References: [CVE-2020-17475], [XFDB-186861]

This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the UPnP service, which listens on TCP port 5000 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-9643.
References: [CVE-2020-10924], [CVE-2020-10923]

A denial of service vulnerability has been identified in Go2Call. The problem is that Go2Call doesn't handle long bogus UDP packets. This allows malicious people to crash the application by sending a 1500 byte long packet to port 5000/udp.
References: [SECUNIA-9673]

SenNet Optimal DataLogger appliance, Solar DataLogger appliance and Multitask Meter could allow a remote attacker to bypass security restrictions, caused by no authentication mechanism implemented for the Telnet service. By connecting to Telnet service using TCP port 5000, an attacker could exploit this vulnerability to bypass access restrictions to connect to the shell and issue commands.

There is no CSRF protection in Liman application. With a little help of social engineering (like sending a link via email/chat) an attacker may force the victim to click on a malicious link, with the purpose of manipulating his current account information, or changing entirely his password. Download the application, make an account and login inside the panel under : expose the docker port on 5000.
References: [EDB-48869]

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6400v2 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the UPnP service, which listens on TCP port 5000 by default. When parsing the uuid request header, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-14110.
References: [CVE-2021-34991]

Backdoor.Win32.BNLite / Remote Heap Based Buffer Overflow - the malware listens on TCP port 5000. Third party attackers who can reach the system can send a specially crafted payload to trigger a heap based buffer overflow overwriting the ECX, EDX registers and corrupting memory located on the heap.
References: [MVID-2021-0407]

Backdoor.Win32.BNLite / Remote Stack Buffer Overflow - BioNet Lite Server 4.0a listens on TCP port 5000. Third-party attackers who can reach an infected system can trigger a buffer overflow overwriting the ECX, EDX and AX (16-bit) registers by sending a long junk payload.
References: [MVID-2022-0502]

The Emerson ROC and FloBoss RTU product lines through 2022-05-02 perform insecure filesystem operations. They utilize the ROC protocol (4000/TCP, 5000/TCP) for communications between a master terminal and RTUs. Opcode 203 of this protocol allows a master terminal to transfer files to and from the flash filesystem and carrying out arbitrary file and directory read, write, and delete operations.

SANS Internet Storm Center: port 5000

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. For more detailed and personalized help please use our forums.
