Vulnerability discussion

Without re-authentication, 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 re-authenticate.Satisfies: SRG-OS-000373-GPOS-00156, SRG-OS-000373-GPOS-00157, SRG-OS-000373-GPOS-00158

Check content

If passwords are not being used for authentication, this is Not Applicable. Verify the operating system requires users to supply a password for privilege escalation. Check the configuration of the "/etc/sudoers" and "/etc/sudoers.d/*" files with the following command: # grep -i nopasswd /etc/sudoers /etc/sudoers.d/* If any uncommented line is found with a "NOPASSWD" tag, this is a finding.

Fix text

Configure the operating system to require users to supply a password for privilege escalation. Check the configuration of the "/etc/sudoers" and "/etc/sudoers.d/*" files with the following command: # grep -i nopasswd /etc/sudoers /etc/sudoers.d/* Remove any occurrences of "NOPASSWD" tags in the file.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
