CVE-2013-0156 Exploit Script

This script is specifically designed to solve the challenge on PentesterLab for the CVE-2013-0156 exploit. You can access the challenge here: PentesterLab - CVE-2013-0156 Challenge.

This Python script is designed to exploit the CVE-2013-0156 vulnerability, a critical remote code execution (RCE) issue in Ruby on Rails applications caused by insecure deserialization of YAML objects. The vulnerability allows an attacker to inject arbitrary code through a crafted YAML payload, leading to code execution on the target server.

Features

• Payload Injection: The script sends a crafted XML payload to the target URL, exploiting the deserialization vulnerability in vulnerable Rails applications (Rails 2.x and 3.x).
• Customizable Target Version: Supports specifying whether the target is Rails 2.x or 3.x, allowing more control over payload format.
• Formatted Output: The script presents a well-structured and visually appealing output with color-coded request and response details, making it easy to track the exploit's status and response.
• Success Notification: Upon successful exploitation, the script notifies the user that the exploit has been executed successfully.

Usage

Installation

Make sure you have the required Python packages installed by running:

pip install requests colorama pyyaml

Running the Script

python exploit.py <URL> <PAYLOAD> [rails3|rails2] [--show ]

Example

  python exploit.py http://example.com/payload example_payload rails3 --show

Example Output

Upon successful execution, the script will display a color-coded output with the following sections:

Request: Shows the URL, headers, and the XML payload being sent. Response: Displays the status code and the response body (truncated for large responses). Success/Failure Notification: Notifies you if the exploit was successful or if any error occurred.

Important Notes

Use Responsibly: This script is designed for educational purposes and should only be used on systems you have permission to test. Unauthorized exploitation of this vulnerability is illegal and unethical. Rails Versions: This script supports Rails 3.x and 2.x. Ensure the target is running a vulnerable version of Rails before attempting the exploit.
