Web client access to the content directories must be restricted to read and execute.

From APACHE SITE 2.2 for Unix Security Technical Implementation Guide

Part of WG290

Associated with IA controls: ECLP-1

SV-33027r1_rule Web client access to the content directories must be restricted to read and execute.

Vulnerability discussion

Excessive permissions for the anonymous web user account are one of the most common faults contributing to the compromise of a web server. If this user is able to upload and execute files on the web server, the organization or owner of the server will no longer have control of the asset.

Check content

To view the value of Alias enter the following command: grep "Alias" /usr/local/apache2/conf/httpd.conf Alias ScriptAlias ScriptAliasMatch Review the results to determine the location of the files listed above. Enter the following command to determine the permissions of the above file: ls -Ll /file-path The only accounts listed should be the web administrator, developers, and the account assigned to run the apache server service. If accounts that don’t need access to these directories are listed, this is a finding. If the permissions assigned to the account for the Apache web server service is greater than Read & Execute (R_E), this is a finding.

Fix text

Assign the appropriate permissions to the applicable directories and files using the chmod command.

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.
