How to fix?

Upgrade Debian:9 ruby2.3 to version 2.3.3-1+deb9u2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby2.3 package and not the ruby2.3 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

The Basic authentication code in WEBrick library in Ruby before 2.2.8, 2.3.x before 2.3.5, and 2.4.x through 2.4.1 allows remote attackers to inject terminal emulator escape sequences into its log and possibly execute arbitrary commands via a crafted user name.
