Kernel mode WinDbg extension and PoCs for testing how token privileges work.
There are notable repository and articles about token privilege abuse such Grzegorz Tworek's Priv2Admin. Codes in this repository are intended to help investigate how token privileges work.
This project covers how to get system privileges from high integrity level shell. See README.md for details.
The purpose of this project is to investigate how attackers abuse arbitrary kernel write vulnerability. All PoCs are written for HackSys Extreme Vulnerable Driver. Most of these PoCs perform to get SYSTEM integrity level by abusing arbitrary kernel write vulnerability and token privileges. Tested on Windows 10 version 1809/1903, but they should work most of Windows 10 theoretically:
| PoC Name | Description |
|---|---|
| CreateAssignTokenVariant | This PoC performs EoP with SeCreateTokenPrivilege and SeAssignPrimaryTokenPrivilege. |
| CreateImpersonateTokenVariant | This PoC performs EoP with SeCreateTokenPrivilege and SeImpersonatePrivilege. |
| CreateTokenVariant | This PoC performs EoP with SeCreateTokenPrivilege. |
| DebugInjectionVariant | This PoC performs EoP with SeDebugPrivilege. Uses code injection to winlogon.exe at final stage. |
| DebugUpdateProcVariant | This PoC performs EoP with SeDebugPrivilege. Creates SYSTEM process from winlogon.exe with UpdateProcThreadAttribute API at final stage. |
| RestoreServiceModificationVariant | This PoC performs EoP with SeRestorePrivilege. Use HijackShellLib with this PoC. |
| SecondaryLogonVariant | This PoC performs EoP with SeCreateTokenPrivilege and SeImpersonatePrivilege. Uses secondary logon service at final stage. |
| TakeOwnershipServiceModificationVariant | This PoC performs EoP with SeTakeOwnershipPrivilege. Use HijackShellLib with this PoC. |
| TcbS4uAssignTokenVariant | This PoC performs EoP with SeTcbPrivilege. Get System mandatory level shell from medium mandatory level. |
| TcbS4uImpersonationVariant | This PoC performs EoP with SeTcbPrivilege. Performs thread impersonation with S4U logon. Not get high or system integrity level. |
Warning
In some environment, Debug build does not work. Release build is preferred.

This project is PoCs for sensitive token privileges such SeDebugPrivilege.
Currently, released PoCs for a part of them.
| Program Name | Description |
|---|---|
| SeAuditPrivilegePoC | This PoC tries to create new security event(s) by SeAuditPrivilegePoC. SeAuditPrivilege does not require high integrity level, but this PoC requires administrative privileges at the first execution to install new event source. Additionally, to confirm the result, this PoC may require modification of local security policy setting. |
| SeBackupPrivilegePoC | This PoC tries to dump HKLM\SAM by SeBackupPrivilege. |
| SeCreatePagefilePrivilegePoC | This PoC tries to set pagefile option to specific values by SeCreatePagefilePrivilege. |
| SeCreateTokenPrivilegePoC | This PoC tries to create a elevated token by SeCreateTokenPrivilege. |
| SeDebugPrivilegePoC | This PoC tries to open a handle to winlogon.exe by SeDebugPrivilege. |
| SeRestorePrivilegePoC | This PoC tries to write test file in C:\Windows\System32\ by SeRestorePrivilege. |
| SeSecurityPrivilegePoC | This PoC tries to read the latest security event by SeSecurityPrivilege. |
| SeShutdownPrivilegePoC | This PoC tries to cause BSOD by SeShutdownPrivilege. |
| SeSystemEnvironmentPrivilegePoC | This PoC tries to enumerate system environment by SeSystemEnvironmentPrivilege. Works for UEFI based system only. Due to OS functionality, this PoC does not work for OSes earlier Windows 10 Build 1809. |
| SeTakeOwnershipPrivilegePoC | This PoC tries to change the owner of HKLM:\SYSTEM\CurrentControlSet\Services\dmwappushservice to the caller user account by SeTakeOwnershipPrivilege. |

If you try S4U logon with unprivileged account for target machine, you will get error

This tool is to execute process as NT SERVICE\TrustedInstaller group account.
Original PoC is Grzegorz Tworek's TrustedInstallerCmd2.c.
I ported it to C# and rebuilt it as a tool.
Most of operations require administrative privilege (SeDebugPrivilege, SeImpersonatePrivilege and High Mandatory Level):
PS C:\Dev> .\TrustExec.exe
TrustExec - Tool to create TrustedInstaller process.
Usage: TrustExec.exe [Options]
-h, --help : Displays this help message.
-l, --lookup : Flag to lookup account name or SID.
-n, --new-console : Flag to create new console. Use with -x flag.
-x, --exec : Flag to execute command.
-a, --account : Specifies account name to lookup.
-c, --command : Specifies command to execute. Default is cmd.exe.
-e, --extra : Specifies command to execute. Default is cmd.exe.
-m, --method : Specifies method ID. Default is 0 (NtCreateToken method).
-s, --sid : Specifies SID to lookup.
Available Method IDs:
+ 0 - Leverages NtCreateToken syscall.
+ 1 - Leverages virtual logon.
+ 2 - Leverages service logon.
+ 3 - Leverages S4U logon.
+ 4 - Leverages TrustedInstaller service.
For this module, 2 techniques are implemeted.
We can specfy a method with -m option.
The value for -m option can be a integer from 0 to 4.
For example, if you set -m option to 0, this tool try to get TrustedInstaller token with NtCreateToken:
PS C:\Dev> .\TrustExec.exe -m 0 -x -c powershell
[*] NtCreateToken syscall method is selected.
[+] SeDebugPrivilege is enabled successfully.
