TMA-APACHE-5.3
Ensure Options for Other Directories Are Minimized
Descripción
The Apache Options directive allows for specific configuration of options, including execution of CGI, following symbolic links, server side includes, and content negotiation. No Options directive inside a <Directory> block may enable Includes, IncludesNOEXEC or All. Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file.

Remove Includes (and All) from Options in every <Directory> block; use only the options each directory needs. Then run apachectl configtest and reload Apache.
