Internet Explorer Processes for restricting pop-up windows must be enforced (iexplore).

Description

<VulnDiscussion>Internet Explorer allows scripts to programmatically open, resize, and reposition various types of windows. Often, disreputable websites will resize windows to either hide other windows or force a user to interact with a window that contains malicious code. The Scripted Window Security Restrictions security feature restricts pop-up windows and prohibits scripts from displaying windows in which the title and status bars are not visible to the user, or which hide other windows' title and status bars. If you enable the Scripted Window Security Restrictions\Internet Explorer Processes policy setting, pop-up windows and other restrictions apply for Windows Explorer and Internet Explorer processes. If you disable or do not configure this policy setting, scripts can continue to create pop-up windows and create windows that hide other windows. This guide recommends configuring this setting to "Enabled" to help prevent malicious websites from controlling the Internet Explorer windows or fooling users into clicking on the wrong window.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
