最新提问 用户: (120 分)

I have a live presentation of this exploit: https://www.exploit-db.com/exploits/41962/

I installed wp 4.6 on my domain, than installed kali linux, however when I execute the bash code I get this output.

output

I checked robots status, allowed all robots to access website.

here you can find the bash script details https://exploitbox.io/vuln/WordPress-Exploit-4-6-RCE-CODE-EXEC-CVE-2016-10033.html

Should I change rev_host="...", I tried website's IP, didn't change the output.

There is video demo: https://www.youtube.com/watch?v=ZFt_S5pQPX0 Is this script is only available for local machines? Or can I do on my live domain, If I can how? Thanks...

The exploit you linked requires a specific (and kinda misconfigured) webserver and a specific mail transfer agent. Your task might be a little more complicated than changing the ip.

A reverse shell attack requires the attacking (eg your kali linux box) machine to be available over internet. rev_host is therefor likely to mean your machines public ip. You will also need to have the correct ports open etc. If you dont understand what the bash script is doing, dont run it.

@Steve You're right. I should do more research. So, I can't attack a domain like website.com
