Opera data: URI dialog spoofing

opera-data-dialog-spoofing (18867) The risk level is classified as MediumMedium Risk

Description:

Opera is a Web browser, developed by Opera Software, for multiple operating systems. Opera version 7.54u1 running on Microsoft Windows could allow a remote attacker to spoof the content in a dialog box. A remote attacker could create a specially-crafted data: URI to cause a malicious file to appear to be a file that is safe for opening. An attacker can use this vulnerability to execute arbitrary code on the victim's system, once the malicious file is downloaded.
