CloudFlair - 🔎 查找CloudFlar背后的网站的源服务器

项目说明

CloudFlair

Important note: As of late 2024, Censys does not provide API access to free accounts anymore. This means CloudFlair does not work with free Censys accounts anymore.

CloudFlair is a 工具 to find origin servers of websites protected by CloudFlare (or CloudFront) which are publicly exposed and don't appropriately restrict 网络 access to the relevant CDN IP ranges.

The 工具 uses Internet-wide scan data from Censys to find exposed IPv4 hosts presenting an SSL certificate associated with the target's domain name. API keys are required and can be retrieved from your Censys account.

For more detail about this common misconfiguration and how CloudFlair works, refer to the companion blog post at <

Here's what CloudFlair looks like in action.

(_The IP addresses in this example have been obfuscated and replaced by randomly generated IPs_)

Setup

1. Register an account (free) on <
2. Browse to < and set two en with your API ID and API secret

3. Clone the repository

4. Create a env and install the dependencies

5. Run CloudFlair (see Usage below for more detail)

or for CloudFront

Usage

Docker image

A lightweight Docker image of CloudFlair (christophetd/cloudflair) is provided. A scan can easily be instantiated using the following command.

You can also create a file containing the definition of the en , and use the Docker--en option.

Compatibility

Tested on Python 3.6. Feel free to open an issue if you have bug reports or questions.
