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.

Security readout for executives and security teams

This is an old Internet Explorer flaw where a crafted FTP link could make the browser send unintended FTP commands. Business risk is mainly legacy exposure: unsupported systems using Internet Explorer 6.0.2800.1106 or earlier may be vulnerable if users open malicious ftp:// URLs. Exposure is limited to systems still running Microsoft Internet Explorer 6.0.2800.1106 or earlier, especially legacy desktops, kiosks, lab systems, or compatibility environments that can open ftp:// URLs. Prioritize this during legacy technology cleanup rather than as an internet-wide emergency. The main concern is unmanaged or business-critical systems still dependent on very old Internet Explorer builds. Mitigation focus: Inventory and remove Internet Explorer 6.0.2800.1106 or earlier from managed environments.; Review Microsoft Security Bulletin MS06-042 for applicable vendor remediation guidance.; Block vulnerable legacy browser use where replacement is not immediately possible..
