Security researcher Juan Pablo Lopez Yacubian
reported that an attacker could call window.open() on an
invalid URL which looks similar to a legitimate URL and then
use document.write() to place content within the new
document, appearing to have come from the spoofed location.
Additionally, if the spoofed document was created by a document with a
valid SSL certificate, the SSL indicators would be carried over into
the spoofed document. An attacker could use these issues to display
misleading location and SSL information for a malicious web page.
