Vulnerability discussion

The "Run as different user" selection from context menus allows the use of credentials other than the currently logged on user. Using privileged credentials in a standard user session can expose those credentials to theft. Removing this option from context menus helps prevent this from occurring.

Check content

If the following registry values do not exist or are not configured as specified, this is a finding. The policy configures the same Value Name, Type and Value under four different registry paths. Registry Hive: HKEY_LOCAL_MACHINE Registry Paths: \SOFTWARE\Classes\batfile\shell\runasuser\ \SOFTWARE\Classes\cmdfile\shell\runasuser\ \SOFTWARE\Classes\exefile\shell\runasuser\ \SOFTWARE\Classes\mscfile\shell\runasuser\ Value Name: SuppressionPolicy Type: REG_DWORD Value: 0x00001000 (4096)

Fix text

Configure the policy value for Computer Configuration >> Administrative Templates >> MS Security Guide >> "Remove "Run as Different User" from context menus" to "Enabled". This policy setting requires the installation of the SecGuide custom templates included with the STIG package. "SecGuide.admx" and "SecGuide.adml" must be copied to the \Windows\PolicyDefinitions and \Windows\PolicyDefinitions\en-US directories respectively.

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.
