    Strumpf Noir Society Advisories
    ! Public release !

    -= Inframail Denial of Service Vulnerability =-

    Release date: Wednesday, March 28, 2001


    Inframail is an advanced SMTP, POP, HTTP and FTP server solution
    available in 3 editions (Home, Small Business and Advantage) for
    MS Windows 9x/NT/2k and Linux.

    Inframail is available from vendor Infradig's website:


    There exists a paring problem in the handling of 302 pages by the
    server serving both the webpages and the administration interface for
    the members of the Inframail product family.

    This allows for a DoS against the system through a malformed POST
    request consisting of a space followed by a long string (276 bytes
    or more) of characters. The running services will freeze and the
    program will need to be restarted to regain full functionality.

    DoS example on the default HTTP port (80):

    # telnet victim 80
    POST / Ax276 bytes/ HTTP/1.1

    after which the running services freeze. The same effect can be
    witnessed when running above on the administration port (default 81).



    Vendor has been notified and has corrected this issue. A new release
    (v3.98a) of this product has been made available from the vendor's

    This was tested against Inframail v3.97a running on MS Windows NT.
