AP7502 captive portal redirection generated parameters

Cristiano_Bevil — Tue, 16 Jan 2018 01:54:00 GMT

I need to understand the URL parameters generated by the redirect captive portal generated when i try to connect to this access point.

The generated URL is, as follows:

code:

http://mycapptiveportal

.com?Qv=it_qpmjdz=Dbqujwf.[ppy@bbb_qpmjdz=BBB.[ppy@dmjfou_njou=2417144::5@dmjfou_nbd=G1.E2.B:.:B.7D.B:@ttje=[ppy_Qspyjpo@bq_nbd=95.35.9E.E9.8G.5B

Someone knows what means these parameters?
Can i get the MAC address from this generated URL?

Thanks!

It is just a simple encoding method to obfuscate the contents in the URL
Subtract 1 from each characters's each ASCII value for everything except _ and =, and @ is separator.
it_qpmjdz = hs_policy=Captive-Zoox
bbb_qpmjdz = aaa_policy = AAA.Zoox
etc...

Now i decoded all the url parameters, as follows:

hs_policy => 'Captive-Zoox'
aaa_policy => 'AAA-Zoox'
client_mint => '1306033994'
client_mac => 'F0-D1-A9-9A-6C-A9'
ssid => 'Zoox_Proxion'
ap_mac => '84-24-8D-D8-7F-4A'

Can you explain me what's the "client_mint"? Is there some way to obtain the client ip address?

And, whats the url parameter "hs_server"? It must be my captive portal address or the controller address?

Thanks!

Hi
I am also interested in knowing what is client_mint
simply if it is a variable of each client, a variable associated with each wifi and the same for all clients or a variable associated with the AP to which it is connected.
Thanks

As far as I can tell, the client_mint is the mint ID of the AP.
If you do DEC->HEX on 1306033994, you get 4D.D8.7F.4A (notice that the last 3 octets are the same as those of ap_mac).
If you run show mint neighbors from CLI, you will see this corresponds to the AP.

Does anyone know how to derive (if possible) the Mint ID first octet from the AP MAC?
