Discussion

Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability, it is critical the user reauthenticate. Satisfies: SRG-OS-000373-GPOS-00156, SRG-OS-000373-GPOS-00157, SRG-OS-000373-GPOS-00158

Check Content

At the command line, run the following commands:

# grep -ihs nopasswd /etc/sudoers /etc/sudoers.d/*|grep -v "^#"|grep -v "^%"|awk '{print $1}'

# awk -F: '($2 != "x" && $2 != "!") {print $1}' /etc/shadow

If any account listed in the first output is also listed in the second output and is not documented, this is a finding.

Fix Text

Check the configuration of the "/etc/sudoers" and "/etc/sudoers.d/*" files with the following command:

# visudo

OR

# visudo -f /etc/sudoers.d/<file name>

Remove any occurrences of "NOPASSWD" tags associated with user accounts with a password hash.
