Adobe Reader DC must disable the ability to elevate IE Trusts to Privileged Locations.
An XCCDF Rule
Description
<VulnDiscussion>Privileged Locations allow the user to selectively trust files, folders, and hosts to bypass some security restrictions, such as enhanced security and protected view. By default, the user can create privileged locations through the GUI. Disabling IE Trusts to Privileged Locations disables and locks the end user's ability to treat IE trusted sites as a privileged location prevents them from assigning trust and thereby exempting that location from enhanced security restrictions.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
