Exposure of information through directory listing

Description

The target web server is configured to list the contents of directories that do not contain an index file such as index.html. This could lead to accidental exposure of sensitive information, or give an attacker details on how filenames and directories are structured and stored.

Remediation

Directory indexing should be disabled.

Apache: For Apache based web sites, ensure all <Directory> definitions have Options -Indexes configured in the apache2.conf or httpd.conf configuration file.

NGINX: For NGINX based websites, ensure all location definitions have the autoindex off directive set in the nginx.conf file.

IIS: For IIS-based websites version 7.0 and later, you can use the <directoryBrowse enabled="false" /> element in the applicationHost.config or Web.config files.

For all other server types, please consult your product’s documentation on how to disable directory indexing.
