## Vulnerable Application
This module exploits a unauthenticated deserialization vulnerability in the XML RPC interface exposed by Zoho
ManageEngine Password Manager Pro before 12101 and PAM360 before 5510. Note that ManageEngine Access Manager Plus
before 4303 is also affected provided one provides credentials, however this is not targeted by this exploit.

Successful exploitation results in unauthenticated RCE as the `NT AUTHORITY\SYSTEM` user.

### Installation
Vulnerable software for testing can be downloaded [here](https://archives2.manageengine.com/passwordmanagerpro/12100/ManageEngine_PMP_64bit.exe).
The patch can be downloaded from [here](https://archives2.manageengine.com/passwordmanagerpro/12101/ManageEngine_PasswordManager_Pro_12100_to_12101.ppm)

When installing the software follow the defaults. You can skip the registration however or any parts where you need
to fill in additional details to continue (these should have a `Skip` button so you can skip them).

## Verification Steps
1. Follow the installation instructions above.
2. Start msfconsole
3. Do: `use exploit/windows/http/zoho_password_manager_pro_xml_rpc_rce`
4. Do: `set RHOSTS [IP]`
7. Do: `set payload [payload]`
8. Do: `set LHOST [IP]`
9. Optional: `set LPORT [local port to listen on]`
10. Do: `exploit`

This module exploits a Java deserialization vulnerability in Zoho ManageEngine Pro
before 12101 and PAM360 before 5510. Unauthenticated attackers can send a
