CVE-2023-42326 exploit

介绍

# pfSense <= 2.7.0 Command Injection Exploit (CVE-2023-42326)

This Python script is a Proof-of-Concept (PoC) exploit for the command injection vulnerability (CVE-2023-42326) in pfSense CE <= 2.7.0 and pfSense Plus <= 23.05.1. The vulnerability allows authenticated attackers to inject and execute arbitrary commands via the `interfaces_gif_edit.php` and `interfaces_gre_edit.php` components.

## Features
- Exploit mode selection (`gif` or `gre`) to choose the vulnerable components.
- Command injection capability to run arbitrary shell commands.
- Netcat reverse shell handling with automatic thread management.
- Debug mode for enhanced visibility of request data.

## Prerequisites
Before running the script, make sure you have:
- Python 3.x installed on your system.
- And run `pip install -r requirements.txt` to make sure the depndecies are satisfied.
- Add a .env file with required variables (explained down bellow) to the projects directory.

## Usage

### Basic Example (Command Injection)

This command executes the exploit and runs the command that you specified in the .env file:

```bash
python3 exploit.py
```

##### .env variables

- `username` --> Username for pfSense admin login
- `password` --> Password for pfSense admin login
- `target` --> Target pfSense IP (e.g., http://10.101.1.1)
- `mode` --> Exploit mode: gif or gre
- `command` --> Command to inject
- `debug` --> Enable debug mode to print response data (True or False)
- `insecure` --> Allow insecure server connections when using SSL (True or False)
### Example Output
When the exploit runs successfully, you should see output similar to this:

```bash
[2024-10-24 03:57:59] [SUCCESS] Target http://10.101.1.1 is reachable
[2024-10-24 03:57:59] [INFO] Fetching CSRF token from: http://10.101.1.1/
[2024-10-24 03:57:59] [SUCCESS] CSRF token extracted successfully
[2024-10-24 03:57:59] [INFO] Sending GIF exploit request to http://10.101.1.1/interfaces_gif_edit.php
[2024-10-24 03:57:59] [SUCCESS] GIF Exploit sent successfully
```

### Notes

- **Privilege Requirement**: You must have valid user credentials for the pfSense instance.
- **Target System**: This exploit is specific to pfSense CE <= 2.7.0 and pfSense Plus <= 23.05.1.
- **Reverse Shell**: Ensure your firewall settings allow incoming connections on the specified port when setting up a reverse shell.

### Debug Mode

If you want to see more details about the requests being sent, you can enable debug mode by adding `-d` to your command. This will print out response data and help you troubleshoot any issues.

### Troubleshooting
- Ensure the target system is reachable.
- Double-check the credentials being used for login.
- Use the `-d` flag for more detailed logging if needed.
