Microsoft Internet Explorer dialog box zone bypass

ie-dialog-zone-bypass (11258) The risk level is classified as MediumMedium Risk


Microsoft Internet Explorer could allow a remote attacker to bypass the cross-domain security model and execute script within the security zone of another domain. Internet Explorer fails to properly verify the origin domain when a dialog box is opened containing script that requests access to another security zone. A remote attacker could exploit this vulnerability by creating a malicious Web page that opens a dialog box containing script, which would be executed in the victim's security zone, once the page is viewed. An attacker could use this vulnerability to read any known file on the victim's computer, gain access to the victim's cookies, invoke known executables on the victim's computer, or load malicious executables to the victim's computer.
