With the above shipping information and payment information in various combinations, they call Thousand API and try to place an order. They inject the code when place an order successfully.

They also try

/rest/english/V1/directory/countries
/rest/V1/directory/countries
/rest/default/V1/directory/countries

API.INFO - Request-Headers: Cookie: PHPSESSID=90d3af9b57b19a50856c5b0d37feef2d; discount_custom=-0 X-Https: 1 Content-Type: application/json; charset=utf-8 User-Agent: Mozilla/5.0 (Linux; Android 11; SM-A205U) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/98.0.4758.87 Mobile Safari/537.36 Content-Length: 490 X-Sucuri-Country: US X-Sucuri-Clientip: 154.30.211.206 X-Real-Ip: 154.30.211.206 X-Forwarded-Proto: https X-Forwarded-For: 154.30.211.206 Host: p*********s.com

The IP of the hacker is abused. https://www.abuseipdb.com/check/154.30.211.206,

Expected result

the spammer is not able to create an order successfully, you should block them to make fack order with native Magento API. This is a misuse of native Magento API. Should Magento protect this API with a token?

Actual result

fack order created with native Magento API.

I have similar issue with a Magento 2 website on version 2.3.5-p7 and lots of orders that are generated with the same format of code.

[Joshua-Trevor-Noeth]

Affecting us as well, on Magento 2.4.6
We have installed the security patch recommended CVE-2024-34102 but it still allows orders and customer account creation through the API unsecured.

Patching is mandatory, but the solution below (creating custom module) is how I complete stopping execution of orders like these:
