# CVE-2025-49113 Roundcube Exploit

A Python exploit for CVE-2025-49113, targeting a vulnerability in Roundcube webmail that allows remote code execution through PHP object deserialization.

## Overview

This exploit leverages a deserialization vulnerability in Roundcube's file upload functionality. It uses a crafted GPG configuration payload to achieve remote code execution on the target server.

## Features

- Automatic authentication with Roundcube
- CSRF token extraction and handling
- Session management
- PHP object deserialization payload generation
- Remote command execution via GPG configuration injection

## Usage

```bash
python exploit.py -t <target_url> -u <username> -p <password> -c <command>
```

### Parameters

- `-t, --target`: Target Roundcube base URL (e.g., `http://example.com/roundcube`)
- `-u, --user`: Valid username for authentication
- `-p, --password`: Password for the specified user
- `-c, --command`: Shell command to execute on the target server

### Example

```bash
python exploit.py -t http://target.com/roundcube -u [email] -p [password] -c "whoami"
```

## How It Works

1. **Authentication**: Logs into Roundcube using provided credentials
2. **Session Management**: Extracts and manages session cookies
3. **Payload Generation**: Creates a serialized PHP object containing the malicious GPG configuration
4. **File Upload**: Uploads a crafted image file with the payload as filename
5. **Code Execution**: The deserialization triggers command execution through GPG configuration

## Technical Details

The exploit targets the `Crypt_GPG_Engine` class deserialization vulnerability by:
- Crafting a base64-encoded shell command
- Embedding it in a serialized PHP object
- Using the object as a filename during file upload
- Triggering deserialization during file processing
