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

Open the IIS 8.5 Manager. Click the IIS 8.5 web server name. Double-click the "Directory Browsing" icon. Under the “Actions” pane verify "Directory Browsing" is disabled. If “Directory Browsing” is not disabled, this is a finding.

Fix text

Open the IIS 8.5 Manager. Click the IIS 8.5 web server name. Double-click the "Directory Browsing" icon. Under the "Actions" pane click "Disabled". Under the "Actions" pane, click "Apply".

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.
