Vulnerability discussion

Directory browsing allows the contents of a directory to be displayed upon request from a web client. If directory browsing is enabled for a directory in IIS, users could receive a web page listing the contents of the directory. If directory browsing is enabled the risk of inadvertently disclosing sensitive content is increased.

Check content

Follow the procedures below for each site hosted on the IIS 8.5 web server: Click the Site. Double-click the "Directory Browsing" icon. If the "Directory Browsing" is not installed, this is Not Applicable. Under the "Actions" pane verify "Directory Browsing" is "Disabled". If "Directory Browsing" is not "Disabled", this is a finding.

Fix text

Follow the procedures below for each site hosted on the IIS 8.5 web server: Open the IIS 8.5 Manager. Click the Site. Double-click the "Directory Browsing" icon. Under the "Actions" pane click "Disabled".

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.
