Title

The ability to override the access configuration for the OS root directory must be disabled. (Cat II impact)

Discussion

The Apache OverRide directive allows for .htaccess files to be used to override much of the configuration, including authentication, handling of document types, auto generated indexes, access control, and options. When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information. When this directive is set to None, then .htaccess files are completely ignored. In this case, the server will not even attempt to read .htaccess files in the file system. When this directive is set to All, then any directive which has the .htaccess Context is allowed in .htaccess files.

Check Content

Locate the Apache httpd.conf file. Open the httpd.conf file with an editor such as notepad, and search for the following uncommented directive: Directory For every root directory entry (i.e. <Directory />) ensure the following entry exists after it: AllowOverride None If the statement above is not found in the root directory statement, this is a finding. If Allow directives are included in the root directory statement, this is a finding. If the root directory statement is not found at all, this is a finding.

Fix Text

Add the following after the Directory directive: AllowOverride None
