With certain browsers (FF 34, Chrome 39 but not IE11) it is still possible to effect a cross-domain redirection using a redirect address having a single slash, e.g. - http://example.com/mantis/login_page.php?return=https:/google.com or - https://example.com/mantis/login_page.php?return=http:/google.com This is essentially the same vulnerability that was described in CVE-2014-6316, but due to a different root cause (for which a patch will be issued soon). I would like to know if I should be using the same CVE ID, or if a new one needs to be issued. Thanks in advance.
