Chargen service running

Description
  • A chargen service is running on this host. The chargen service was intended for testing and measurement purposes and may listen on both TCP and UDP protocols. Upon opening a TCP connection, the server starts sending arbitrary characters to the connecting host and continues until the hosts closes the connection. In the UDP version of the protocol, the server sends a UDP packet containing a random number (between 0 and 512) of characters every time it receives a UDP packet from the connecting host. Any data received by the server is thrown away.<br/> The chargen service can be spoofed into sending data from one service on one computer to another service on another computer. This action causes an infinite loop and creates a denial of service attack.
Remediation
  • It is recommended to disable this service.
