# Insufficient CSRF protection (CVE-2012-5683)
# All sensitive functions are lacking CSRF protection. One example below is
a request showing no authorization token is required for the creation of a
FTP user called "fun". This could also be used to deliver both XSS
(CVE-2012-5684) and SQLi (CVE-2012-5685) examples below.

# SQL Injection (CVE-2012-5685)
# "inEmailAddress" parameter is vulnerable to SQL injection. Since the
injection point is in an UPDATE statement its trivial to manipulate the
content of the database. For instance the zadmin password could be changed
to password.(5f4dcc3b5aa765d61d8327deb882cf99)

# One more sqli example
# A user can extract data from db though an UPDATE statement by using a
subquery. As long as we update a field that is displayed back to us. To
reproduce this example you need to know your ClientID which can be found in
the referring page's url as the value of "other". In this example we use
the email field to hold the result of the subquery. Usually you can't
select from the table you're updating but by creating a temporary table
called "fun" we can avoid that. Using group_concat we get all columns and
all rows as a single string so that it all fits nicely in a single field.

# Password Reset Weakness, Insufficient entropy (CVE-2012-5686)
# "randomkey" is not sufficiently random. By knowing server time an
attacker could reset a password and guess the key within a relatively low
number of requests.  If the attacker can receive a password reset email for
any account on the system (demo account?) the number of attempts required
to guess reset key for another user (zadmin) can be greatly reduced.  Since
the zadmin default admin account is "hard coded" it is especially at risk
to this password reset weakness. If you change zadmin username in the
zpanel_core db my experience is that you cannot load zpanel control panel.
