CRLF injection vulnerability in Microsoft Internet Explorer 6.0.2800.1106 and earlier allows remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded newline ("%0a") before the FTP command, which causes the commands to be inserted into the resulting FTP session, as demonstrated using a PORT command.
