# Ollama CVE-2024-39722 Exploit Tool

This tool is designed to exploit CVE-2024-39722, a model existence disclosure vulnerability in Ollama versions up to and including 0.1.45. It allows users to check if an Ollama server is vulnerable and attempt to discover existing models on the server. Additionally, it can crawl the official Ollama model library to generate a list of potential models for testing.
[中文](README_zh.md)

## Vulnerability Details

*   **CVE ID:** CVE-2024-39722
*   **Description:** Ollama versions <= 0.1.45 are vulnerable to a model existence disclosure. By sending a specially crafted request to the `/api/push` endpoint, an attacker can determine if a specific model (including custom models not in the public library) exists on the server.
*   **Affected Versions:** <= 0.1.45
*   **CVSS Score:** 7.5 (High)

## Features

*   **Crawl Ollama Model Library:** Fetches the list of models from the official Ollama library (`https://ollama.com/library`).
*   **Version Check:** Checks if the target Ollama server version is vulnerable.
*   **Exploit Vulnerability:** Attempts to discover existing models on a vulnerable Ollama server using a list of known model names.
*   **Multi-threaded Exploitation:** Uses multiple threads for faster model discovery.
*   **Output Results:** Saves crawled models and leaked models to a JSON file.

## Requirements

*   Python 3.x
*   `requests`
*   `lxml`
*   `termcolor`

## Installation

1.  Clone the repository or download the script `CVE_2024_39722.py`.
2.  Install the required Python packages:
    ```bash
    pip install requests lxml termcolor
    ```

## Usage

```bash
python CVE_2024_39722.py [options]
```

### Options

*   `-h, --help`: Show the help message and exit.
*   `-u URL, --url URL`: Target Ollama server URL (e.g., `http://localhost:11434`).
*   `-c, --crawl`: Crawl Ollama models library and save them to `links.json`.
*   `-o OUTPUT, --output OUTPUT`: Output file for results (default: `results.json`).
*   `-t THREADS, --threads THREADS`: Number of threads to use for exploitation (default: 10).
*   `-v, --version-check`: Only check if the target Ollama server is vulnerable based on its version.

### Examples

1.  **Show help:**
    ```bash
    python CVE_2024_39722.py -h
    ```

2.  **Crawl Ollama model library:**
    This will fetch model names from `https://ollama.com/library` and save them to `links.json`.
    ```bash
    python CVE_2024_39722.py --crawl
    ```

3.  **Check if a target server is vulnerable:**
    ```bash
    python CVE_2024_39722.py -u http://localhost:11434 --version-check
    ```

4.  **Exploit a target server:**
    This will first check the server's version. If vulnerable, it will use the `links.json` (crawl if not present or use existing) to test for model existence.
    ```bash
    python CVE_2024_39722.py -u http://localhost:11434
    ```

5.  **Exploit with a specific number of threads:**
    ```bash
    python CVE_2024_39722.py -u http://localhost:11434 -t 20
    ```

6.  **Exploit and save results to a custom file:**
    ```bash
    python CVE_2024_39722.py -u http://localhost:11434 -o discovered_models.json
    ```
