Vulnerability Discussion

Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised.

Check

Remove the telnet package from the Ubuntu operating system by running the following command:

# sudo apt-get remove telnetd

Fix

Verify that the telnet package is not installed on the Ubuntu operating system.

Check that the telnet daemon is not installed on the Ubuntu operating system by running the following command:

# dpkg -l | grep telnetd

If the package is installed, this is a finding.
