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.
