Ghost CMS Vulnerability Exploit

[henning410]

In your paper, you mentioned:
"The vulnerability was found and confirmed in the version 1.19.2, but the version from 1.17.x to 1.19.x are also affected. The exploit was made for the version 1.19.2"

I installed ghost with npm install [email protected] -g and ghost install local.
Unfortunately, when I send the payload with Burp Suite, I get the following error:

HTTP/1.1 404 Not Found X-Powered-By: Express Content-Version: v5.44 Vary: Accept-Version, Accept-Encoding Cache-Control: no-cache, private, no-store, must-revalidate, max-stale=0, post-check=0, pre-check=0 Content-Type: application/json; charset=utf-8 Content-Length: 204 ETag: W/"cc-YCoG45/D6BWkqoZEAdMKM3pX01k" Date: Tue, 25 Apr 2023 11:18:21 GMT Connection: close {"errors":[{"message":"Resource not found","context":null,"type":"NotFoundError","details":null,"property":null,"help":null,"code":null,"id":"e361c270-e35a-11ed-bbaa-570fac3ca52d","ghostErrorCode":null}]}

Maybe something is wrong with my ghost version, or I do something wrong with Burp. Can you help me out here?
