Risk Level: Medium risk vulnerability  Medium

Check or Attack Name: rootdotdot

Platforms: NCSA Servers: Old
Description:

A directory listing was obtained of the directory above the root directory of the web server. A URL of the form http://www.domain.com/..\.. allows anyone to browse and download files outside of the web server content root directory. URLs such as http://www.domain.com/scripts..\..\script-name allow you to execute the target script. An attacker can use a listing of this directory as additional information for planning a structured attack, or could download files elsewhere in the file system.

Remedy:

Check with the vendor and documentation of your web server software for information on the correct configuration. If necessary, install a more recent (and secure) version of the web server.

The latest version of Microsoft Internet Information Server (IIS) is available at http://www.microsoft.com/iis.
