Subject: RE: Multiple Vendor FTP pipe Vulnerability

Securityfocus has a post on its website regarding this vulnerability in
many ftp clients.  I've tested and subsequently validated this issue on
many of the platforms mentioned in their advisory.  They mention
that the Netscape client on Windows 2000 Professional, but fails to
mention that the commandline ftp client included with win2k (server and
pro) are also vulnerable.

# Create file on ftp server for download by client.

# Start commandline ftp client on win2k.
