Loading vulnerability…
A vulnerability in Microsoft Internet Explorer 10 and 11 allows local attackers to enumerate the existence of files on the local system. The issue arises because IE loads different files for file:// URLs depending on whether the file exists, and HTML5 sandboxed iframes suppress error dialogs, enabling detection of file existence via the iframe's onload event. This can be exploited locally or from a network share, but not from regular websites due to file:// URL restrictions. The vulnerability does not affect earlier IE versions lacking HTML5 sandbox support.
