Vulnerability discussion

The ability of Outlook to automatically turn text that represents Internet and network paths into hyperlinks would allow users to click on those hyperlinks in email messages and access malicious or otherwise harmful websites.

Check content

The intent of this check is to block the display of Internet and network paths as hyperlinks in email messages. This requirement cannot be configured in the Office 2010 Administrative Templates. It can either be configured individually, within each Outlook client, or by registry key. To verify within the Outlook client that "Internet and network path into hyperlinks" is not enabled: From the main Outlook window, go to Tools>>Options. Select the "Mail Format" tab. Select the "Editor Options" button. In the left pane, select the "Proofing" button. Select the "AutoCorrect" button. Select the "AutoFormat As You Type" tab. Criteria: If the "Internet and network path into hyperlinks" checkbox is selected, this is a finding. Procedure: Use the Windows Registry Editor to navigate to the following key: HKCU\software\policies\Microsoft\office\14.0\outlook\options\autoformat Criteria: If the value pgrfafo_25_1 is REG_DWORD = 1, this is a finding.
