    token        Get AdminService access token
    admin        Add user as SCCM admin

options:
  -h, --help     show this help message and exit

```

```
➜  CVE-2025-59501 git:(main) ✗ uv run poc.py token -h
usage: poc.py token [-h] -u USERNAME [-p PASSWORD] -c CLIENT_ID -t TENANT_ID [-s SCOPE]

                        entra tenant ID
  -s, --scope SCOPE     resource URI/Scope
