Microsoft Windows XP Remote Desktop Plaintext Username Vulnerability

Microsoft Windows XP Remote Desktop Plaintext Username Vulnerability

Microsoft Windows XP Remote Desktop transmits user account names in plain text over the network when a connection is initiated. The account name sent is not necessarily the user account name on the remote machine; it is the most recent user account used by the remote desktop client. A sniffer could potentially capture traffic on a network and discover user account names, especially when repeated connections are being made to a particular machine from Remote Desktop clients.
