      FGatePro Multiple Vulnerabilities (Path Disclosure, CSS, Username
    Exposure)
    ------------------------------------------------------------------------

    SUMMARY

     <http://www.ftgate.com/> FTGatePro "contains all the features you would
    expect from a world-class mail server, including anti-virus integration,
    sophisticated anti-SPAM options, comprehensive IP security features, NT
    SAM integration, SMTP/ESMTP, web server, web mail, LDAP, POP3, SmartPop,
    attachment filters, mail filters, system monitoring, MX delivery, dial-up
    facilities, scheduling, user mailboxes, list mailboxes, group mailboxes,
    robot mailboxes, autoresponder mailboxes and list servers. FTGatePro is
    fully compatible with Windows NT/2000/XP".

    The product has been found to contain multiple vulnerabilities allowing a
    remote attacker to cause the server to reveal the true path under which it
    is installed, to return arbitrary HTML and JavaScript code as if it were
    its own, and to inform the attacker whether the username he provided is
    valid or not.

    DETAILS

    Vulnerable systems:
     * FTGatePro version 1.22 build 1331

    Path Disclosure:
    By requesting the following URL:
    http://127.0.0.1:8089/utility/wmsecurity.fts, the following response will
    be received:
     Error in C:\Program Files\FTGate\Webs\WebAdmin\utility\wmsecurity.fts
    line 13, Undeclared Identifier 'null'

    This will allow a remote attacker to reveal the true path under which the
    product was installed.

    Cross Site Scripting:
    By requesting such a URL as: http://127.0.0.1:8089/help/index.fts?href=<
    script>alert('C.S.S')</script> it is possible to insert malicious HTML
    and/or JavaScript into pages that are returned by the server (this in turn
    will allow hijacking of accounts, etc).

    Remote User Verification:
    Because the server responds differently for invalid usernames and valid
    username, it is possible to determine whether a user provided username is
    valid.

    Example:
       Telnet 127.0.0.1 110
        
       +OK POP3 FTGatePro server ready
       user InValid

       -ERR InValid doesn't get mail here

       user user1
       +OK user1 gets mail here
