Title

Saved from URL - Access (Cat II impact)

Discussion

Typically, when Internet Explorer loads a web page from a UNC share that contains a Mark of the Web (MOTW) comment that indicates the page was saved from a site on the Internet, Internet Explorer runs the page in the Internet security zone instead of the less restrictive Local Intranet security zone. This functionality can be controlled separately for instances of Internet Explorer spawned by 2007 Office applications (for example, if a user clicks a link in an Office document or selects a menu option that loads a web page). If Internet Explorer does not evaluate the page for a MOTW, potentially dangerous code could be allowed to run.
