I'm trying to analyze log from my rails applications I sometimes see hits from random IP addresses that look like this:
-------------------------------
Request:
-------------------------------
* URL : https://${ip}/
* HTTP Method: GET
* IP address : 162.62.191.231
* Parameters : {"controller"=>"runner", "action"=>"index"}
* Timestamp : 2022-08-17 18:28:07 +0300
* Server : b82b789929df
* Rails root : /root/my_app
* Process: 270
Those are not some replacement to hide IP from you, it seems like literally request with https://${ip}/ value
But not sure from where it's coming, probably some guys are testing my site for some vulnerability, but I cannot detect which.
https://${ip}/ is a really bad string to google it
And especially I cannot understand how to simulate the same request with curl or wget to see if it really safe
