Service name

This is only possible to takeover if http://vulnerabledomain.ghost.io/ghost/#/signin is redirect to https://offline.ghost.org/#/signin (where vulnerable domain is vulnerable host like adminpatel etc. )

Proof

go to https://adminpatel.ghost.org/ghost/#/signin and takeover it

Hello good afternoon!!

Is this acquisition still possible?

[Kaue-Navarro]

YES, I CONFIRME is possible acquisition!

domain.com is an alias for xxxxx.ghost.io.

In the case I was testing it was not possible, here the detail:

target.domain.com alias for target2.ghost.io

Tried to create an account/site using target2 but it was created as target2-2. And when I tried to change it manually, displayed an error message to contact support.

First you create a common site there you will get a pseudonym from them.

Then in the account you change it.

So if your case was not the same as mine in terms of configuration within the platform by the target host.

But see my article if it helps you understand the process.
