This module exploits command injection vulnerability in the ManageEngine Application Manager product.
An unauthenticated user can execute a operating system command under the context of privileged user.
Publicly accessible testCredential.do endpoint takes multiple user inputs and validates supplied credentials
by accessing given system. This endpoint calls a several internal classes and then executes powershell script
without validating user supplied parameter when the given system is OfficeSharePointServer.
