to an information disclosure vulnerability." );

"The remote host is running the Spam Quarantine Management web
component of MailMarshal SMTP, a mail server for Windows. 

The version of the Spam Quarantine Management web component installed
on the remote host fails to sanitize input to the 'emailTextBox'
parameter of the 'Register.aspx' script before using it in database
queries.  By appending a long string of blanks and his own email
address, an unauthenticated attacker may be able to leverage this
issue to reset and retrieve the password to any user account provided
he knows the email address associated with it." );
