    FS Advisory ID: FS-062502-22-AXSH

    Release Date: June 25, 2002

    Product: AnalogX SimpleServer:Shout

    Vendor: AnalogX (http://www.analogx.com)

    Vendor Advisory: See vendor web site

    Type: Buffer Overflow

    Severity: High

    Author: Robin Keir (robin.keirfoundstone.com)
                                    Foundstone, Inc.
    (http://www.foundstone.com)

    Operating Systems: Windows variants

    Vulnerable versions: SimpleServer:Shout v1.0

    Foundstone Advisory: http://www.foundstone.com/advisories.htm
    ---------------------------------------------------------------------

    Description

    A buffer overflow exists in AnalogX's SimpleServer:Shout software.
    Exploitation of this vulnerability allows remote execution of arbitrary
    code with the privileges of the Shout daemon (default is SYSTEM).

    Details

    Sending a fake request to the target system on TCP port 8001 consisting
    of a packet of 348 or more non-space characters followed by 2 carriage
    return linefeeds causes a write access violation in the application.
    Manually dismissing the application error message box that is displayed
    on the affected system at this point will terminate the process. If the
    message box is not manually dismissed,, repeated sending of the request
    causes repeated access violation message boxes to appear on the affected
    system to the point where the service no longer responds.

    Different number of bytes sent cause different error conditions to
    occur, such as write access violations and Watcom memory error dialogs
    to appear.

    Solution:

    Refer to the vendor's web site for further details:

    Credits:

    Foundstone would like to thank AnalogX for their prompt response and
    handling of this problem.
