THC-Hydra with password only login form

[nigco]

I’m trying to get THC-Hydra working on a website form which doesn’t require a username just the password. It is a local site of my router If I load IP then this site is comming up:

 

http://IP:PORT/ui/dynamic/guest-login.html?mac_addr=8c%3A70%3A5a%3Af4%3A0f%3A6c&url=http%3A%2F%2Fdetectportal.firefox.com%2Fsuccess.txt&ip_addr=172.30.192.144

 

I loadet the site via Bump suit and this is the result:

POST /JNAP/ HTTP/1.1

{"macAddress":"8c:70:5a:f4:0f:6c","ipAddress":"XXX.30.192.144","password":"lol"}

Wrong password this appears on the site: Invalid guest password. Please try again.

 

This is my command:

hydra XXX.30.192.189:10080 http-form-post "/ui/dynamic/guest-login.html?mac_addr=8c%3A70%3A5a%3Af4%3A0f%3A6c&url=http%3A%2F%2Fdetectportal.firefox.com%2Fsuccess.txt&ip_addr=XXX.30.192.144:guest-pass=^PASS^:F=Invalid guest password. Please try again.:" -l ''  -P toplel.txt

 

But the comment is not working correctly because I get the response all passwords are true. Is my command syntax wrong?
