This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. UDP is often used with time-sensitiveĪpplications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data. The message to process any errors and verify correct delivery. Like TCP, UDP is used in combination with IP (the Internet Protocol)Īnd facilitates the transmission of datagrams from one computer to applications on another computer,īut unlike TCP, UDP is connectionless and does not guarantee reliable communication it's up to the application that received Guaranteed communication/delivery is the key difference between TCP and UDP. TCP guarantees delivery of dataĪnd that packets will be delivered in the same order in which they were sent.
To establish a connection and exchange streams of data. TCP ports use the Transmission Control Protocol, the most commonly used protocol Used port numbers for well-known internet services. IANA is responsible for internet protocol resources, including the registration of commonly Ports are unsigned 16-bit integers (0-65535) that identifyĪ specific process, or network service. Port numbers in computer networking represent communication endpoints.
List of all used ports:Ĭisco 11000 Series Content Services Switches (CSS) running WebNS 5.0(x) before 05.0(04.07)S, and 6.10(x) before 06.10(02.05)S allow remote attackers to cause a denial of service (device reset) via a malformed packet to UDP port 5002. The device can be viewed/controlled through a range of Linux/Windows DVR/PVR programs. HDHomeRun can be administered over the Ethernet link to tune channels, broadcast an MPEG stream, etc. HDHomeRun DVR from SiliconDust uses this port. It broadcasts periodically looking for Drobo NAS devices to manage. Some other trojans also use this port: cd00r, Shaft, Linux Rootkit IV (4)ĭrobo Dashboard's discovery uses port 5002 UDP. IPv6 is also left in auto-configuration mode, accepting router advertisements automatically and assigns a MAC address based IPv6 address. As the process is running as "root" full control over the device can be acquired. Still the Equinox console port 5002 is left open, allowing to log into Kura without any user credentials over unencrypted telnet and executing commands using the Equinox "exec" command. The network enabled distribution of Kura before 2.1.0 takes control over the device's firewall setup but does not allow IPv6 firewall rules to be configured. This is caused by an Unrestricted Externally Accessible Lock. The affected Ethernet interface module is connected to a MELSEC-Q PLC, which may allow a remote attacker to connect to the PLC via Port 5002/TCP and cause a denial of service, requiring the PLC to be reset to resume operation. References: Īn issue was discovered in Mitsubishi Electric Automation MELSEC-Q series Ethernet interface modules QJ71E71-100, all versions, QJ71E71-B5, all versions, and QJ71E71-B2, all versions. Unspecified vulnerability in HP LoadRunner 9.52 allows remote attackers to execute arbitrary code via network traffic to TCP port 5001 or 5002, related to the HttpTunnel feature. The service must be restarted to regain normal functionality. A remote attacker could send a specially-crafted HTTP request to the HTTP server listening on port 5002 to cause the service to crash. SouthWest is vulnerable to a denial of service attack. Opens a backdoor on one or more of these ports: 1927, 1930, 5002, 5003
Spreads through network shares, MySQL (port 3306)/MS SQL (port 1433) servers with weak passwords, and by exploiting system vulnerabilities (ports 135, 445). (2005.01.26) - Worm with distributed denial of service and backdoor capabilities.
