**JuicyPotato doesn't work** on Windows Server 2019 and Windows 10 build 1809 onwards. However, [**PrintSpoofer**](https://github.com/itm4n/PrintSpoofer)**,** [**RoguePotato**](https://github.com/antonioCoco/RoguePotato)**,** [**SharpEfsPotato**](https://github.com/bugch3ck/SharpEfsPotato) can be used to **leverage the same privileges and gain `NT AUTHORITY\SYSTEM`** level access. _**Check:**_
## Juicy Potato (abusing the golden privileges) <a href="#juicy-potato-abusing-the-golden-privileges" id="juicy-potato-abusing-the-golden-privileges"></a>
_A sugared version of_ [_RottenPotatoNG_](https://github.com/breenmachine/RottenPotatoNG)_, with a bit of juice, i.e. **another Local Privilege Escalation tool, from a Windows Service Accounts to NT AUTHORITY\SYSTEM**_
#### You can download juicypotato from [https://ci.appveyor.com/project/ohpe/juicy-potato/build/artifacts](https://ci.appveyor.com/project/ohpe/juicy-potato/build/artifacts)
[RottenPotatoNG](https://github.com/breenmachine/RottenPotatoNG) and its [variants](https://github.com/decoder-it/lonelypotato) leverages the privilege escalation chain based on [`BITS`](https://msdn.microsoft.com/en-us/library/windows/desktop/bb968799\(v=vs.85\).aspx) [service](https://github.com/breenmachine/RottenPotatoNG/blob/4eefb0dd89decb9763f2bf52c7a067440a9ec1f0/RottenPotatoEXE/MSFRottenPotato/MSFRottenPotato.cpp#L126) having the MiTM listener on `127.0.0.1:6666` and when you have `SeImpersonate` or `SeAssignPrimaryToken` privileges. During a Windows build review we found a setup where `BITS` was intentionally disabled and port `6666` was taken.
We decided to weaponize [RottenPotatoNG](https://github.com/breenmachine/RottenPotatoNG): **Say hello to Juicy Potato**.
> For the theory, see [Rotten Potato - Privilege Escalation from Service Accounts to SYSTEM](https://foxglovesecurity.com/2016/09/26/rotten-potato-privilege-escalation-from-service-accounts-to-system/) and follow the chain of links and references.
We discovered that, other than `BITS` there are a several COM servers we can abuse. They just need to:
1. be instantiable by the current user, normally a “service user” which has impersonation privileges
* **Process to launch** _launch an executable or script if the exploitation succeeds_
* **Process Argument** _customize the launched process arguments_
* **RPC Server address** _for a stealthy approach you can authenticate to an external RPC server_
* **RPC Server port** _useful if you want to authenticate to an external server and firewall is blocking port `135`…_
* **TEST mode** _mainly for testing purposes, i.e. testing CLSIDs. It creates the DCOM and prints the user of token. See_ [_here for testing_](http://ohpe.it/juicy-potato/Test/)
If the user has `SeImpersonate` or `SeAssignPrimaryToken` privileges then you are **SYSTEM**.
It’s nearly impossible to prevent the abuse of all these COM Servers. You could think about modifying the permissions of these objects via `DCOMCNFG` but good luck, this is gonna be challenging.
The actual solution is to protect sensitive accounts and applications which run under the `* SERVICE` accounts. Stopping `DCOM` would certainly inhibit this exploit but could have a serious impact on the underlying OS.
Oftentimes, the default CLSID that JuicyPotato uses **doesn't work** and the exploit fails. Usually, it takes multiple attempts to find a **working CLSID**. To get a list of CLSIDs to try for a specific operating system, you should visit this page:
First, you will need some executables apart from juicypotato.exe.
Download [Join-Object.ps1](https://github.com/ohpe/juicy-potato/blob/master/CLSID/utils/Join-Object.ps1) and load it into your PS session, and download and execute [GetCLSID.ps1](https://github.com/ohpe/juicy-potato/blob/master/CLSID/GetCLSID.ps1). That script will create a list of possible CLSIDs to test.
Then download [test\_clsid.bat ](https://github.com/ohpe/juicy-potato/blob/master/Test/test\_clsid.bat)(change the path to the CLSID list and to the juicypotato executable) and execute it. It will start trying every CLSID, and **when the port number changes, it will mean that the CLSID worked**.
