He pointed to the address bar of one screenshot that showed usa.kaspersky.com along with the text "concat_ws(0x3a,ver" to the right of that. "It's a URL that is being used to alter the database request that's used to generate the page," he added. "One of them can be tricked into pulling arbitrary data from the database. Game over."
