Adding user accounts to Local DB via a Captive Portal web form

L4 Transporter

I was wondering if there's a way to create a web form on the Captive Portal so that a user could create their own account and have it added to the PAN Local DB via an API?

Thanks,

Jeff

The captive portal response page can only be a single page, however it might be technically possible to create that page with a javascript powered form that could add a user to the local DB.  It looks like the API call you'd use would be this:

/api/?type=config&action=set&xpath=/config/shared/local-user-database/user/entry[@name='joeuser']&element=<phash>$1$shsipcfw$qQcH/MlxYG1ucCdhTkkMs/</phash>

Of course you'll notice that the above command contains a phash, which we can also generate via the API

/api/?type=op&cmd=<request><password-hash><password>test</password></password-hash></request>

Note that both of the above api calls work as-is if you are currently logged in to the firewall as a superuser.  For a js form you wouldn't be, so you would need to generate an API key and use it in your calls.

As always, even with obfuscation the API key is potentially extractable and could be used for other purposes, so it's best to ensure that this is only used in a trusted environment.

Thank you very much!  Tried it from my browser and it worked great!  Now just need to test it out with a CP Response Page.

When you get it working, please share a sanitized version on DevCenter!
