Title

Directory indexing must be disabled on directories not containing index files. (Cat II impact)

Discussion

Directory options directives are directives that can be applied to further restrict access to file and directories. If a URL which maps to a directory is requested, and there is no DirectoryIndex (e.g., index.html) in that directory, then mod_autoindex will return a formatted listing of the directory which is not acceptable.

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: Options Review all uncommented Options statements for the following value: -Indexes If the value is found on the Options statement, and it does not have a preceding “-”, this is a finding. If the value does not exist, this would be a finding unless the enabled Options statement is set to “None”.

Fix Text

Add a "-" to the Indexes setting, or set the options directive to None.
