Title

If the system is using LDAP for authentication or account information, the TLS certificate authority file and/or directory (as appropriate) must be owned by root. (Cat II impact)

Discussion

LDAP can be used to provide user authentication and account information, which are vital to system security. The LDAP client configuration must be protected from unauthorized modification.

Check Content

Check if the system is using NSS LDAP. # grep -v '^#' /etc/nsswitch.conf | grep ldap If no lines are returned, this vulnerability is not applicable. Verify the ownership of the certificate database files. # ls -lL /var/ldap/cert8.db /var/ldap/key3.db /var/ldap/secmod.db If the owner of any of the files is not root, this is a finding.

Fix Text

Change the ownership of the certificate database files. # chown root /var/ldap/cert8.db /var/ldap/key3.db /var/ldap/secmod.db
