# Green Hills INTEGRITY RTOS F-16 Exploit - CVE-2019-7711
**Full Format String Exploitation Chain**
**Realistic Ground Maintenance Attack on F-16 Avionics**
---
## ๐ Description
This repository contains a **Proof of Concept (PoC)** for **CVE-2019-7711** โ a Format String vulnerability in the Interpeak IPCOMShell TELNET server (part of Green Hills INTEGRITY RTOS 5.0.4).
The exploit demonstrates a **realistic full attack chain** targeting the **F-16 Fighting Falcon** (Block 60 and similar) Color Display Processor (CDP) and mission systems during **ground maintenance**.

## โ ๏ธ Important Disclaimer
- This exploit is for **educational and research purposes only**.
- Real F-16 aircraft use strict partitioning (ARINC 653). Networking services are typically disabled in flight.
- Do **NOT** use this on any operational aircraft or unauthorized systems.
- Unauthorized access to military avionics is illegal.
---
## โจ Features
- Realistic F-16 ground maintenance scenario
- Strong memory leak phase
- Arbitrary memory write using `%n` primitive
- Control flow hijack trigger
- Clean and educational code structure
---
## ๐ ๏ธ Usage
```bash
python3 exploit.py [--lhost ] [--lport ]
```
**Example:**
```bash
python3 exploit.py 192.168.1.100
```
---
## ๐ How to Use (Step by Step)
1. Run the exploit against a vulnerable TELNET maintenance interface
2. Analyze the **Memory Leak** output (Phase 1)
3. Adjust the `%n` offset in Phase 2 based on the leak
4. Execute the full chain
---
## โ๏ธ Requirements
- Python 3.x
- Target running INTEGRITY RTOS 5.0.4 with IPCOMShell enabled (lab environment only)
