> This extension identifies hidden, unlinked parameters. It's particularly useful for finding web cache poisoning vulnerabilities.
|
||||
|
||||
## Exploit
|
||||
|
||||
1. Browser requests `http://www.example.com/home.php/non-existent.css`.
|
||||
1. Browser requests a resource such as `http://www.example.com/home.php/non-existent.css`.
|
||||
2. Server returns the content of `http://www.example.com/home.php`, most probably with HTTP caching headers that instruct to not cache this page.
|
||||
3. The response goes through the proxy.
|
||||
4. The proxy identifies that the file has a css extension.
|
||||
5. Under the cache directory, the proxy creates a directory named home.php, and caches the imposter "CSS" file (non-existent.css) inside.
|
||||
|
||||
## Methodology of the attack - example
|
||||
|
||||
## Methodology - Caching Sensitive Data
|
||||
|
||||
**Example 1** - Web Cache Deception on PayPal Home Page
|
||||
1. Normal browsing, visit home : `https://www.example.com/myaccount/home/`
|
||||
2. Open the malicious link : `https://www.example.com/myaccount/home/malicious.css`
|
||||
3. The page is displayed as /home and the cache is saving the page
|
||||
4. Open a private tab with the previous URL : `https://www.paypal.com/myaccount/home/malicous.css`
|
||||
4. Open a private tab with the previous URL : `https://www.example.com/myaccount/home/malicous.css`
|
||||
5. The content of the cache is displayed

|
||||
|
||||
## Methodology 2
|
||||
**Example 2** - Web Cache Deception on OpenAI
|
||||
1. Attacker crafts a dedicated .css path of the `/api/auth/session` endpoint.
|
||||
2. Attacker distributes the link
|
||||
3. Victims visit the legitimate link.
|
||||
4. Response is cached.
|
||||
5. Attacker harvests JWT Credentials.
|
||||
|
||||
|
||||
## Methodology - Caching Custom JavaScript
|
||||
|
||||
1. Find an un-keyed input for a Cache Poisoning

|
||||
|
||||
## CloudFlare Caching
|
||||
|
||||
CloudFlare caches the resource when the `Cache-Control` header is set to `public` and `max-age` is greater than 0.
|
||||
|
||||
- The Cloudflare CDN does not cache HTML by default
|
||||
- Cloudflare only caches based on file extension and not by MIME type: [cloudflare/default-cache-behavior](https://developers.cloudflare.com/cache/about/default-cache-behavior/)
|
||||
|
||||
CloudFlare has a list of default extensions that gets cached behind their Load Balancers.
