GreenPlasma is a C++ security research project that demonstrates an elevation-of-privileges vulnerability in Windows CTFMON through arbitrary section creation. The tool targets a specific weakness in the Collaborative Translation Framework Monitor service, allowing researchers to exploit the flaw and gain higher system privileges. It lives at the intersection of exploit development and capture-the-flag competitions, where understanding real Windows internals matters.

The project was created by Nightmare-Eclipse and currently sits at 475 GitHub stars. It is not a general-purpose exploit kit but a focused demonstration of a single vulnerability class. The code is available on GitHub.

Core features

  • CTFMON arbitrary section creation exploit — Demonstrates a privilege escalation path through the Windows CTFMON service.
  • C++ implementation — Written in C++, with direct interaction with Windows APIs and memory structures.
  • CTF-focused design — Built with capture-the-flag environments in mind, where controlled exploit demonstration is the goal.
  • Proof of concept — Provides a working exploit rather than just a theoretical explanation, useful for security research and training scenarios.

Getting it running

GreenPlasma is a C++ project, so you will need a Windows development environment with the appropriate SDK. Clone the repository and build with your preferred C++ compiler. There is no package manager install step — the project is source-only.

git clone https://github.com/Nightmare-Eclipse/GreenPlasma.git
cd GreenPlasma
# Build with your C++ toolchain (MSVC, MinGW, etc.)

No Dockerfile or language-level package is provided. The README context does not detail specific build flags or dependencies beyond the C++ language itself.

Who this is for

This project is aimed at security researchers, CTF players, and anyone studying Windows privilege escalation techniques. If you are preparing for a red team assessment or learning exploit development on Windows, GreenPlasma gives you a concrete example of how CTFMON can be abused. It is also useful for defenders who want to understand the mechanics of the vulnerability.

Keep in mind that running exploits on a live system carries real risk. The intended environment is isolated test machines or CTF platforms where privilege escalation is the exercise.

How it compares

Most publicly available privilege escalation tools on Windows are broader in scope — for example, WinPEAS enumerates many possible escalation paths, while GTFOBins catalogs known escalation techniques across operating systems. GreenPlasma is narrower. It targets one specific vulnerability in one specific Windows component. That focus makes it a better learning resource for the CTFMON exploit specifically, but it will not replace a general enumeration tool.

GTFOBins (gtfobins.github.io) covers many privilege escalation vectors but does not focus on CTFMON. WinPEAS (github.com/carlospolop/PEASS-ng) offers broad enumeration but lacks exploit code for this particular flaw. GreenPlasma fills that gap with working code.

Honest summary

GreenPlasma is a focused, single-purpose exploit written in C++ that demonstrates how CTFMON on Windows can be used for privilege escalation through arbitrary section creation. It is not a toolkit — it is a proof of concept tied to one vulnerability. For researchers and CTF participants who need a concrete example of this exploit, it is a small but specific resource.
