Discussion

Enabling user environment processing may enable users to bypass access restrictions in some configurations and must therefore be disabled.

Check Content

At the command line, run the following command to verify the running configuration of sshd:

# sshd -T|&grep -i PermitUserEnvironment

Example result:

permituserenvironment no

If "PermitUserEnvironment" is not set to "no", this is a finding.

Fix Text

Navigate to and open:

/etc/ssh/sshd_config

Ensure the "PermitUserEnvironment" line is uncommented and set to the following:

PermitUserEnvironment no

At the command line, run the following command:

# systemctl restart sshd.service
