Disclaimers

• This is considered to be a beta release, and may contain bugs and unintentional behavior. Consider yourself warned!

Requirements

DiffCD requires HTTPDiff and HTTPInsert and can be install with python3 -m pip install httpdiff httpinsert or python3 -m pip install -r requirements.txt.

Why

Why create another content discovery tool when so many already exists?

Most (not all) content discovery tools rely solely on status codes for determining which endpoints "exists". Many applications have endpoints that are hidden due to the status code being the same as non-existant endpoints. Some websites even changes the reason phrase(!) and nothing else for certain endpoint. These types of behavior is really interesting when performing a pentest and can yield information about configuration etc. Relying only on the status code is a poor strategy resulting in subpar output. HTTPDiff analyzes all parts of the response; the status code, reason, headers, body, response times, errors, etc., this allows to find some interesting endpoints impossible to find with traditional tools, or even manually.

DiffCD uses HTTPDiff to determine the normal behavior of an application and checks for any differences when scanning for endpoints. This way it is possible to find endpoints based on any change of behavior, not only limited to the status code!
