## Description
This module exploits a remote command execution vulnerablity in Hewlett Packard Enterprise Intelligent Management Center before version 7.3 E0504P04.
The dbman service allows unauthenticated remote users to restore a user-specified database (OpCode 10007), however the database connection username is not sanitized resulting in command injection, allowing execution of arbitrary operating system commands as SYSTEM. This service listens on TCP port 2810 by default.
## Vulnerable Application
[HPE Intelligent Management Center Enterprise Software Platform](https://www.hpe.com/au/en/product-catalog/networking/intelligent-management-software/pip.hp-intelligent-management-center-enterprise-software-platform.4176520.html) is a comprehensive wired and wireless network management tool.
This module has been tested successfully on:
* iMC PLAT v7.2 (E0403) on Windows 7 SP1 (EN).
Installer:
* [iMC PLAT v7.2 (E0403) Standard](https://h10145.www1.hpe.com/Downloads/DownloadSoftware.aspx?SoftwareReleaseUId=16759&ProductNumber=JG747AAE&lang=en&cc=us&prodSeriesId=4176535&SaidNumber=)
## Verification Steps
1. Start `msfconsole`
2. Do: `use exploit/windows/misc/hp_imc_dbman_restoredbase_unauth_rce`
3. Do: `set RHOST <IP>`
4. Do: `run`
5. You should get a session
## Scenarios
```
msf > use exploit/windows/misc/hp_imc_dbman_restoredbase_unauth_rce
msf exploit(windows/misc/hp_imc_dbman_restoredbase_unauth_rce) > set rhost 172.16.191.166
rhost => 172.16.191.166
msf exploit(windows/misc/hp_imc_dbman_restoredbase_unauth_rce) > set verbose true
verbose => true
msf exploit(windows/misc/hp_imc_dbman_restoredbase_unauth_rce) > check
