MEDIUM: Open QOTD Report

DESCRIPTION LAST UPDATED: 2023-12-18

DEFAULT SEVERITY LEVEL: MEDIUM

This report identifies hosts that have the Quote of the Day (QOTD) service running and accessible on the Internet.

These services have the potential to be used in amplification attacks by criminals that wish to perform denial of service attacks. The service is tested by sending a UDP packet containing a single carriage return to UDP port 17.

You can track latest QOTD exposure on our Dashboard.

Severity levels are described here.
