Vulnerability discussion

When Microsoft Office files are opened from trusted locations, all the content in the files is enabled and active. Users are not notified about any potential risks that might be contained in the files, such as unsigned macros, ActiveX controls, or links to content on the Internet.By default, users can specify any location as a trusted location, and a computer can have a combination of user-created, OCT-created, and Group Policy–created trusted locations.

Check content

The policy value for User Configuration -> Administrative Templates -> Microsoft Office 2010 -> Security Settings -> Trust Center “Allow mix of policy and user locations” must be set to “Disabled”. Procedure: Use the Windows Registry Editor to navigate to the following key: HKCU\Software\Policies\Microsoft\Office\14.0\common\security\trusted locations Criteria: If the value Allow User Locations is REG_DWORD = 0, this is not a finding.

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.
