    Vendor Name: MondoSoft
    Vendor URL: http://www.mondosoft.com
    Vendor contacted: 15-Sep-2003

    Problem:
    MondoSearch is web site search engine made by MondoSoft.

    MsmSetup.exe is one of the programs in the default installation. This
    program contains a vulnerability that makes it possible to create files
    with user specified content on the webserver or anywhere else, where the
    executing user (typically IUSR_xxx) has write access.

    Details:
    The vulnerability occurs when the Msmsetup.exe is called with a
    specially crafted querystring.

    Impact:
    It is possible for a malicious user to, create and execute arbitrary ASP
    code on the server. This could in turn, lead to a full compromise of the
    server.

    Corrective actions:
    MondoSoft has released a patch for this issue.
