Vulnerability discussion

The /etc/pam_user.conf file is the per user configuration file for the Pluggable Authentication Module (PAM) architecture. It supports per user authentication, account, session, and password management. If the configuration is modified maliciously, users may gain unauthorized system access. The /etc/pam_user.conf file must not be configured unless it is required.

Check content

If the system is configured for Trusted Mode, this check is not applicable. For SMSE: Verify the file has no extended ACL. # ls -lL /etc/pam_user.conf If the permissions include a “+”, the file has an extended ACL, this is a finding.

Fix text

If the system is operating in Trusted Mode, no fix is required. For SMSE: Remove the optional ACL from the file. # chacl -z /etc/pam_user.conf

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.
