Vulnerability discussion

Users can subscribe to RSS feeds from within Outlook and read RSS items like e-mail messages. If your organization has policies that govern the use of external resources such as RSS feeds, allowing users to subscribe to the RSS feed in Outlook might enable them to violate those policies.

================================== NOTE: Some operational environments may elect to allow use of RSS feeds integrated into Outlook, provided there is a mission need and the network environment meets the following criteria: - both the web site issuing the RSS feeds and the Outlook e-mail client both have an available network path to each other - neither the web site issuing the RSS feeds nor the Outlook e-mail client have a network path to the public Internet. An example of such an environment would be a closed lab or other deployed network where the requisite signoffs, artifacts, and network documentation demonstrate that the Public Internet is not available to the Outlook client, preventing unauthorized RSS subscriptions being accessed by users of the Outlook client. The policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2010 -> Account Settings -> RSS Feeds “Turn off RSS feature” must be set to “Disabled”. Use the Windows Registry Editor to navigate to the following key: HKCU\Software\Policies\Microsoft\Office\14.0\outlook\options\rss Criteria: If the environment meets the above stated criteria, and value "Disable" is REG_DWORD = 0, this is not a finding. For all environments where the Outlook e-mail client has access to public Internet web sites, RSS integration into Outlook is not permitted, and should be validated as follows. ================================= The policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2010 -> Account Settings -> RSS Feeds “Turn off RSS feature” must be set 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.
