Vulnerability discussion

If users are able to manually enter the addresses of servers that are not approved by the organization, they could use servers that do not meet your organization's information security requirements, which could cause sensitive information to be at risk.By default, when users create a meeting workspace, they can choose a server from a default list provided by administrators or manually enter the address of a server that is not listed.

Check content

Verify the policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2013 -> Meeting Workspace "Disable user entries to server list" is set to "Enabled (Publish default, disallow others)". Procedure: Use the Windows Registry Editor to navigate to the following key: HKCU\Software\Policies\Microsoft\Office\15.0\meetings\profile Criteria: If the value ServerUI is REG_DWORD = 2, this is not a finding.

Fix text

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2013 -> Meeting Workspace "Disable user entries to server list" to "Enabled (Publish default, disallow others)".

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.
