# CVE-2025-63406 – Security Research Proof-of-Concept (PoC)
This repository contains a **research-oriented Proof of Concept (PoC)** related to the security issue **CVE-2025-63406**, affecting the **GroupOffice** platform.
The purpose of this project is to **study and understand the vulnerability’s behavior**, assist security teams in **risk evaluation**, and help validate **patches and mitigations** in controlled environments.
> ⚠️ **Important Notice**
> This PoC is provided **strictly for authorized security research, auditing, and educational analysis**.
> It must **not** be used against systems without explicit permission.

## 🔍 About the Vulnerability
CVE-2025-63406 describes a condition in which internal handling of GroupOffice objects—specifically **FieldSet**, **Field**, and **Task** entities—may lead to unintended behavior under certain circumstances.
This project aims to:
- Analyze how the vulnerability can manifest.
- Explore how logical chains involving *create/update/destroy* operations behave.
- Demonstrate the API flow and internal state transitions.
- Help researchers replicate and validate the issue in a safe, isolated environment.
The provided source code focuses on the **logic flow**, not on enabling exploitation.
---
## 🧩 Code Overview
The PoC script demonstrates:
- URL normalization and input sanitization.
- Authentication flow using GroupOffice’s API.
- Retrieval and management of session cookies and CSRF tokens.
- Creation and removal of **FieldSet** and **Field** objects.
- Interaction with the **JMAP API** (`/api/jmap.php`).
- Extraction and inspection of server-side state responses.
- Identification and cleanup of previously created research artifacts.
This structure is intended for analysis and understanding of internal behavior rather than practical exploitation.
---
## 🧪 Research Goals
This PoC assists researchers in:
- Understanding how the vulnerability arises.
- Reproducing the logical sequence of events internally.
- Observing object handling mechanisms inside GroupOffice.
- Testing and validating vendor patches in a controlled environment.
---
## ⚙️ Environment Requirements
To run the PoC in a **safe, isolated research environment**, you will need:
- Python **3.10+**
- The `requests` library
- A controlled, local, test-only instance of GroupOffice affected by CVE-2025-63406
