# CVE-2019-1040-dcpwn

Great writeup! [Exploiting CVE-2019-1040 - Combining relay vulnerabilities for RCE and Domain Admin](https://dirkjanm.io/exploiting-CVE-2019-1040-relay-vulnerabilities-for-rce-and-domain-admin/) .

So, I wrote dcpwn.py for easy to use.

## Requirements
These tools require [impacket](https://github.com/SecureAuthCorp/impacket). You can install it from pip
```
pip install impacket
```

## Usage
```
usage: dcpwn.py [-h] [-u USERNAME] [-p PASSWORD] [--hashes HASHES] -d DOMAIN
                [--smb-port [destination port]] --callback-ip CALLBACK_IP
                --ldaps LDAPS --dc-ip DC_IP [--timeout TIMEOUT]
                [--impersonate IMPERSONATE] -t Target [-share SHARE]
                [--command [COMMAND [COMMAND ...]]] [--debug]

  --dc-ip DC_IP         Domain controller ip address
  --timeout TIMEOUT     timeout in seconds

                        target username that will be impersonated (thru
                        S4U2Self) for quering the ST. Keep in mind this will
                        only work if the identity provided in this scripts is
                        allowed for delegation to the SPN specified

If you  want to execute some command like cmd.exe.  use `--command`

```

If you  want to impersonate specified user,  use `--impersonate`
