SV-63289r1_rule If the system is using LDAP for authentication or account information, the TLS certificate authority file and/or directory (as appropriate) must have mode 0644 (0755 for directories) or less permissive.

Vulnerability 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

Determine the certificate authority file and/or directory. Procedure: # grep -i '^tls_cacert' /etc/ldap.conf For each file or directory returned, check the permissions. Procedure: # ls -lLd If the mode of the file is more permissive than 0644 (or 0755 for directories), this is a finding.

Fix text

Change the mode of the file or directory. File Procedure: # chmod 0644 Directory Procedure: # chmod 0755

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.
