SV-52724r2_rule Rights managed Office Open XML files must be protected.

Vulnerability discussion

When Information Rights Management (IRM) is used to restrict access to an Office Open XML document, any metadata associated with the document is not encrypted. This configuration could allow potentially sensitive information such as the document author and hyperlink references to be exposed to unauthorized individuals.

Check content

Verify the policy value for User Configuration >> Administrative Templates >> Microsoft Office 2013 >> Security Settings "Protect document metadata for rights managed Office Open XML Files" is set to "Enabled". Use the Windows Registry Editor to navigate to the following hive: HKEY_Users For every users profile hive under HKEY_Users, navigate to the following key: \Software\Policies\Microsoft\Office\15.0\common\security If the value “DRMEncryptProperty” is REG_DWORD = 1 for every user profile hive, this is not a finding.

Fix text

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Office 2013 -> Security Settings "Protect document metadata for rights managed Office Open XML Files" 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.
