Hacking Sur La Table's Kiosk

So I was perusing around our local Sur La Table and came across this

(to the left is a Cisco VoIP phone that it was plugged in to)

Needless to say it caught my attention.

I tried the 3 finger salute, I tried the Windows button, and the windows + D button and I wasn't getting anywhere.

So I started to poke around the menus and all that I had access to was the website.
No URL bar, no right click to open in new window or save as.

So I was wondering how I could get to another website to potentially download an command prompt or something, when I only have access to their website?

Well their website is vulnerable to XSS which allowed me to do a document.location"><script>document.location='';</script>&s=true

as you can see by:

Another potentional option would have been via their home page, is their ads to their twitter and facebook pages.

So obviosuly they didn't have a whitelist/blacklist of URLs to visit.

I was not able to exploit any further, as my significant other was catching on to what I was doing.

But with it being tied into the Cisco phones, I would place a bet that it is tied into the same system as the cash registers. (just speculating here)

So happy hacking!

Very nice! If you can't download/execute files, perhaps you could use some js to find out what the browser is, see if it has known exploits..

edit: You can probably access the POS system with the free wifi but that's boring
