Vulnerability discussion

Some features may communicate with the vendor, sending system information or downloading data or components for the feature. Turning off this capability will prevent potentially sensitive information from being sent outside the enterprise and uncontrolled updates to the system. This setting prevents the client computer from printing over HTTP, which allows the computer to print to printers on the intranet as well as the Internet.

Check content

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\Windows NT\Printers\ Value Name: DisableHTTPPrinting Value Type: REG_DWORD Value: 1

Fix text

Configure the policy value for Computer Configuration >> Administrative Templates >> System >> Internet Communication Management >> Internet Communication settings >> "Turn off printing over HTTP" to "Enabled".

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.
