Vulnerability discussion

Outlook users can create and use signatures in e-mail messages. Users can add signatures to messages manually, and can also configure Outlook to automatically append signatures to new messages, to replies and forwards, or to all three. Signatures typically include details such as the user's name, title, phone numbers, and office location. If your organization has policies that govern the distribution of this kind of information, using signatures might cause some users to inadvertently violate these policies.

Check content

The policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2010-> Outlook Options -> Mail format “Do not allow signatures for e-mail messages” 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\mailsettings Criteria: If the value DisableSignatures is REG_DWORD = 0, this is not a finding.

Fix text

Set the policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2010-> Outlook Options -> Mail format “Do not allow signatures for e-mail messages” to “Disabled”.

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.
